The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage media) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0042] User input unit 107 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as touch screen, can collect touch operations on or near the user (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0043] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides corresponding visual output on the display panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal.

Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0046] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.

[0047] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0048] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0049] To facilitate understanding of the embodiments of this application, the communication network system on which the mobile terminal of this application is based is described below.

It selects and provides available policy and charging control decisions for the policy and charging enforcement function unit (not shown in the figure).

[0054] IP services 204 may include the Internet, intranet, IMS (IP Multimedia Subsystem), or other IP services.

[0055] Although the above description uses the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation.

[0056] Based on the above-described mobile terminal hardware structure and communication network system, various embodiments of this application are proposed.

[0057] First Embodiment Reference Figure 3 , Figure 3 This is a flowchart illustrating the interaction method according to the first embodiment. The interaction method of this application embodiment can be applied to a terminal (e.g., a smartphone, feature phone, etc.) and includes the following steps (e.g., steps S10 to S20): S10: Execute a USSD interaction request operation based on the first USSD character sequence to establish a USSD session channel and obtain the interaction menu of the interaction terminal corresponding to the first USSD character sequence.

[0058] S20: In response to the selection of an interactive item in the interactive menu, the interactive process corresponding to the selected interactive item is executed in collaboration with the interactive terminal through the USSD session channel.

[0059] Optionally, the first USSD character sequence may represent a series of specific characters entered in the USSD (Unstructured Supplemental Service Data) service and be used to interact with the network operator platform (such as the system of a mobile network operator) to request or perform specific services or operations.

[0060] Optionally, the format of a USSD character sequence typically begins with an asterisk (*), followed by numbers containing commands or data. Groups of numbers can be separated by additional asterisks, and the sequence terminates with a hash symbol (#), such as "*861*81#", "*101#", or "*139*1*1234567890#". Optionally, as technology advances, the format of a USSD character sequence can also be other than this.

[0061] Optionally, the first USSD character sequence can be uniquely associated with a specific interactive terminal or a specific interactive menu of a specific interactive terminal.

[0062] Optionally, in step S10, performing a USSD interaction request operation based on the first USSD character sequence can represent sending a session request to the network operator platform through the input first USSD character sequence, so that the network operator platform can establish a USSD session channel with the interaction terminal corresponding to the first USSD character through the USSD gateway.

[0063] Optionally, the interactive menu on the interactive terminal may include one or more interactive items, and each interactive item may be associated with the same or different interactive processes. Optionally, each interactive process corresponds to a service that the interactive terminal can provide.

[0064] Optionally, the interactive terminal can represent the terminal (e.g., mobile phone, cash register, etc.) or service operating system (e.g., a system consisting of a terminal and a web platform, etc.) used by the service provider.

[0065] Optionally, by coordinating with the interactive terminal through the USSD session channel to execute the interaction process corresponding to the selected interaction item, it can be represented that specific information is sent and / or received between the USSD session channel and the interactive terminal, so that the interactive terminal can complete the provision of specific services.

[0066] Optionally, the application scenarios of the interaction method provided in this embodiment include, but are not limited to, consumption scenarios, financial service scenarios, public service scenarios, healthcare scenarios, transportation and logistics scenarios, and agricultural scenarios. Optionally, in consumption scenarios, services such as mobile payment and coupon redemption are provided by the service provider corresponding to the interaction terminal. Optionally, in financial service scenarios, services such as account balance inquiry and fund transfer are provided by the bank corresponding to the interaction terminal. Optionally, in public service scenarios, information services such as weather forecasts, news headlines, and stock quotes are provided by the service provider corresponding to the interaction terminal. Optionally, in healthcare scenarios, services such as doctor appointments, medical information inquiries, and health advice are provided by the service provider corresponding to the interaction terminal. Optionally, in transportation and logistics scenarios, services such as road condition inquiries, bus schedules, and flight information are provided by the service provider corresponding to the interaction terminal. Optionally, in agricultural scenarios, services such as crop planting information and pest and disease control advice are provided by the service provider corresponding to the interaction terminal.

[0067] In some implementations, each service's interactive item provided by the interactive terminal needs to be uniquely associated with a specific USSD character sequence. Therefore, when the interactive terminal provides various services to the user, the user needs to view or memorize the corresponding USSD character sequences for each service, making the operation cumbersome and inconvenient. However, the technical solution provided in this embodiment allows the user to intuitively see the selectable interactive items by obtaining and displaying the interactive menu of the interactive terminal using a single USSD character sequence. This enables the user to easily trigger the corresponding interactive process by simply selecting an item from the menu, thus meeting the user's interactive needs without the need for complex memorization. Therefore, the technical solution of this embodiment can realize USSD-based interactive functionality, allowing users to interact with the interactive terminal intuitively and conveniently using USSD, simplifying the operation and improving the user experience.

[0068] Second Embodiment The interaction method of the second embodiment of this application can be applied to consumer scenarios and / or financial service scenarios of terminals (such as smartphones, feature phones, etc.), including the following steps (e.g., steps S10 to S20): S10: Execute a USSD interaction request operation based on the first USSD character sequence to establish a USSD session channel and obtain the interaction menu of the interaction terminal corresponding to the first USSD character sequence.

[0069] S20: In response to the selection of an interactive item in the interactive menu, the interactive process corresponding to the selected interactive item is executed in collaboration with the interactive terminal through the USSD session channel.

[0070] Optionally, each interactive item in the interactive menu corresponds to a service that the service provider at the interactive terminal can provide in the consumption scenario and / or financial service scenario, such as ticket redemption service (e.g., redeeming coupons), consumption payment service, time-based billing service, recharge service, recharge balance inquiry service, etc.

[0071] Optionally, service providers in consumer scenarios include, for example, various merchants. Service providers in financial service scenarios include, for example, banks.

[0072] Optionally, step S2O includes, but is not limited to, at least one of the following: In response to the selection of the first interactive item, the ticket acquisition process is executed in collaboration with the interactive terminal through the USSD session channel; In response to the selection of the second interactive item, the consumer payment process is executed in collaboration with the interactive terminal through the USSD session channel. In response to the selection of a third interactive item, the timing and billing process is executed in collaboration with the interactive terminal through the USSD session channel. In response to the selection of the fourth interactive item, the recharge and payment process is executed in collaboration with the interactive terminal through the USSD session channel; In response to the selection of the fifth interactive item, the balance query process is executed in collaboration with the interactive terminal through the USSD session channel.

[0073] Optionally, the ticket acquisition process is executed in conjunction with the interactive terminal, including at least one of the following: Receive at least one ticket information from the interactive terminal; In response to a ticket redemption operation based on the ticket information, the system retrieves the ticket sent by the interactive terminal, which includes identification information for verification.

[0074] Thus, the technical solution of this embodiment can conveniently obtain tickets (e.g., coupons) through USSD to support the ticket collection and usage needs in consumption scenarios.

[0075] Optionally, the consumption payment process is executed in conjunction with the interactive terminal, including at least one of the following: Receive and display billing information sent from the interactive terminal; Obtain and send payment information to the interactive terminal so that the interactive terminal can perform a payment collection operation based on the payment account corresponding to the payment information; Receive and display the payment result after the payment is received by the interactive terminal.

[0076] Optionally, in some on-site consumption scenarios, the billing information can be viewed by the user on-site (e.g., the user can view it directly on the interactive terminal, or the merchant can inform the user directly). Therefore, in the consumption payment process, "receiving and displaying the billing information sent by the interactive terminal" is an optional step.

[0077] Optionally, billing information may represent data that records and reflects user spending details and / or other relevant financial information.

[0078] Alternatively, payment information can represent various information required to enable the interactive terminal to perform a payment collection operation from a specific payment account.

[0079] Optionally, the payment information includes, but is not limited to, at least one of the following: payment account information, payment amount information, ticket identification information, and payment item name.

[0080] Optionally, the payment account information includes, but is not limited to, at least one of bank account information, a second USSD character sequence, etc.

[0081] Optionally, the bank account information includes, but is not limited to, at least one of the following: account identification information, payment verification code, and payment password.

[0082] Optionally, the second USSD character sequence can represent a series of specific characters entered in the USSD (Unstructured Supplemental Service Data) service and be used to interact with the network operator platform (such as the system of a mobile network operator) so that the network operator platform can use the specific payment account corresponding to the second USSD character sequence to support the payment collection operation of the interactive end.

[0083] Optionally, the payment result returned by the interactive terminal after completing the payment operation can indicate whether the payment was successful or failed.

[0084] Thus, the technical solution of this embodiment can realize the USSD payment function, so as to conveniently complete the consumption payment through USSD.

[0085] Compared to Near Field Communication (NFC) payment, the USSD payment function provided in this embodiment has lower hardware requirements and is more suitable for users in areas with low NFC terminal coverage. Compared to QR code payment, the USSD payment function provided in this embodiment has lower reliance on high-speed networks, no security vulnerabilities such as static QR code replacement or payment code screenshotting and fraudulent transactions, and no requirements for light or cameras. Compared to mobile banking application payment functions, the USSD payment function provided in this embodiment has lower reliance on high-speed networks and does not require the installation of security plugins. In addition, the USSD payment function provided in this embodiment is applicable not only to smart terminals but also to feature phones, while the aforementioned Near Field Communication (NFC), QR code, and mobile banking application payment functions are not suitable for feature phones and are not suitable for areas with unstable high-speed networks and low banking service penetration (such as Africa).

[0086] Alternatively, a feature phone can be defined as a mobile phone device with basic communication functions (such as voice calls and text messages) and some simple additional functions.

[0087] In some regions, banking service penetration is low, making it difficult for feature phone users to access financial services. For example, in Africa, only 25% of users have bank cards, and Unbank users also have a strong desire to access financial services and have the ability to make payments. The convenience, security, tracking and management capabilities, and online-offline integration of digital payments are making them an increasingly integral part of users' daily lives. While smartphone penetration is rapidly increasing, allowing smartphone users to enjoy payment services offered by MMOs, feature phones lack online payment capabilities. Feature phone users can only fulfill their daily needs through offline bank branches or agents, such as basic services like transfers, top-ups, and data transfers. Feature phone users also need a more convenient and secure digital payment environment. Considering network and data costs, the USSD payment function provided in this embodiment can meet the digital payment needs of feature phone users, compensating for the lack of online payment channels and allowing them to enjoy the convenience of digital payments, thus improving the user experience.

[0088] Optionally, the USSD payment function provided in this embodiment can be enhanced with identity verification, such as combining a unique session ID and SIM card PIN code with USSD operations to improve account security and enhance user trust.

[0089] Optionally, payment information is acquired and sent to the interactive terminal, enabling the interactive terminal to perform a payment collection operation based on the payment account corresponding to the payment information. This includes: inputting the total payment amount and the number of payers to initiate an AA payment request; responding to the initiation of the AA payment request by inputting multiple payment account information based on the number of payers to acquire payment information, the payment account information including bank account information and / or a second USSD character sequence; and sending the payment information to the interactive terminal, enabling the interactive terminal to perform a payment collection operation on the payment account corresponding to each payment account based on the acquired average collection amount, and to feed back the payment result to the corresponding terminal based on each second USSD character sequence.

[0090] Thus, the technical solution of this embodiment allows users to quickly initiate an AA (Average Amount) payment request simply by entering the total payment amount and the number of payers, eliminating the need to enter the payment amount for each individual, greatly simplifying the operation and saving time and effort. Furthermore, this embodiment's technical solution can use not only bank account information as the basis for associating a specific payment account, but also the second USSD character sequence. Therefore, the interactive terminal can perform a payment collection operation on the associated specific payment account based on the bank account information and / or the second USSD character sequence. Additionally, the second USSD character sequence can also serve as the communication basis for the terminals of AA payment participants, allowing the payment result to be fed back to the AA payment participants based on the second USSD character sequence. Therefore, the technical solution of this embodiment provides a USSD-based AA (Average Amount) payment function.

[0091] Optionally, payment information is acquired and sent to the interactive terminal, enabling the interactive terminal to perform a payment collection operation based on the payment account corresponding to the payment information. This includes: adding the identification information of the ticket obtained through the ticket acquisition process to the payment information; sending the payment information to the interactive terminal, enabling the interactive terminal to perform a payment collection operation on the payment account corresponding to the payment account information in the payment information, and performing a ticket redemption operation based on the identification information in the payment information. Thus, the technical solution of this embodiment can integrate the use and redemption of tickets (e.g., coupons) into the USSD payment function.

[0092] Optionally, in response to initiating an AA payment request, the step of entering multiple payment account information based on the number of payers to obtain payment information may include adding the identification information of the tickets obtained during the ticket acquisition process to the payment information. Thus, ticket (e.g., coupon) redemption can also be performed in the USSD-based AA payment function.

[0093] Optionally, the timing and billing process is executed in collaboration with the interactive terminal, including: sending preset information to the interactive terminal to enable the interactive terminal to start timing and billing; and / or, in response to the end of billing operation, obtaining the billing information fed back by the interactive terminal and executing the consumption payment process to control the interactive terminal to end timing and billing.

[0094] Optionally, the preset information can be an instruction to start billing or identification information of the billing object. For example, in a parking consumption scenario, the identification information of the billing object can be at least one of vehicle information (such as license plate number) or terminal identification (such as SIM card PIN code).

[0095] Thus, the USSD payment function provided by the technical solution of this embodiment can be applied to time-based consumption scenarios.

[0096] Optionally, the interaction method provided in this embodiment (e.g., before step S10) further includes: enabling the USSD interaction function when the SIM card's home location matches the current region. Thus, enabling the USSD interaction function when the SIM card's home location matches the current region can avoid problems such as network latency, high costs, or service unavailability caused by roaming. When users use the USSD function locally, they can enjoy faster response times and more stable connections, improving the interactive experience.

[0097] The interaction method of this embodiment can be applied to consumption scenarios and / or financial service scenarios of terminals (such as smartphones, feature phones, etc.), and can provide USSD payment function, coupon redemption function, and USSD-based AA payment function. Furthermore, the use and redemption of tickets (such as coupons) and time-based consumption can be integrated into the USSD payment function.

[0098] Third Embodiment See Figure 4 The third embodiment of this application provides an interactive system, including: a terminal 301, a network operator platform 302, a USSD gateway 303, and an interactive terminal 304.

[0099] The terminal 301 is used to send a session request to the network operator based on the first USSD character sequence, so that the network operator platform 302 can establish a USSD session channel with the interactive terminal 304 corresponding to the first USSD character through the USSD gateway 303.

[0100] Optionally, terminal 301 may implement the steps of the interaction method as described in the first or second embodiment.

[0101] The interactive terminal 304 is used to feed back the interactive menu to the terminal 301 through the USSD session channel, so that the terminal 301 receives the interactive menu and responds to the selection operation of the interactive item in the interactive menu, and works with the interactive terminal 304 through the USSD session channel to execute the interactive process corresponding to the selected interactive item.

[0102] In the interactive system provided in this embodiment, the terminal 301 can enable the network operator platform 302 to establish a USSD session channel with the interactive terminal 304 corresponding to the first USSD character through the USSD gateway 303 via the first USSD character sequence, and can obtain the interactive menu of the interactive terminal 304, so that the user can directly see one or more interactive items to choose from, and the user can trigger the interactive process corresponding to the selected interactive item by performing a simple selection operation on the interactive item in the interactive menu, so as to meet the user's interactive needs.

[0103] Based on the same inventive concept as the foregoing embodiments, the foregoing embodiments will be illustrated below through examples of solutions in consumer scenarios: Prerequisite services completed by the service provider (interactive end): ① Complete the application and activation of the USSD number segment; ② USSD Development: Complete the USSD account opening process to obtain a USSD account, and develop the corresponding interactive processes for various consumption services (such as the development of interactive processes for transfer services, balance inquiry services, and airtime (USSD phone bill recharge) services). ③ Connect the corresponding interfaces; ④ Ensure that the USSD account can operate normally and continuously.

[0104] See Figure 5 Service interaction process: 1. User device initiates USSD request: The user initiates the payment service by dialing a specific USSD code (i.e., the first USSD character sequence) through the user device (i.e., the terminal); 2. Mobile network service provider transmits request to USSD gateway: Mobile network operator (i.e., network operator platform) receives USSD request and establishes session with USSD gateway; 3. The USSD gateway sends the USSD code to the service provider: After the USSD gateway sends the USSD code to the service provider (i.e., the interactive end), a USSD session channel is formed; 4. Service providers generate dynamic service menus: Dynamic service menus (i.e., interactive menus) can include options for recharge services, balance inquiry services, coupon services, etc. 5. Service provider returns dynamic service menu to user device: Service provider returns dynamic service menu to user device via USSD session channel; 6. The user device displays a dynamic service menu; 7. User device selects service options and enters information: Users navigate to the information input field by selecting the corresponding number for the service, and receive instructions based on the service options and input information, which are then transmitted to the mobile network service provider. The input information includes payment amount, coupon information, recipient account, payment verification code, payment password, etc. 8. The mobile network service provider transmits instructions to the USSD gateway; 9. The USSD gateway forwards instructions to the service provider; 10. The service provider verifies and processes the transaction and provides the processing result: The service provider verifies and processes the transaction according to the information corresponding to the instruction (e.g., balance inquiry service, fee calculation, deduction, etc.), and the processing result includes failure or success. SMS notification may also be provided if necessary. 11. Service provider returns processing results to user equipment: The service provider returns processing results to the user equipment via the USSD session channel; 12. The user device takes corresponding actions based on the processing result: When the processing result indicates failure, the processing result may also include failure information and post-failure service operation information, so that the user can take corresponding actions through the user device.

[0105] Based on the same inventive concept as the foregoing embodiments, the following examples of solutions for parking billing scenarios will be used to illustrate the foregoing embodiments: See Figure 6 Scenarios where feature phones can conveniently and dynamically pay parking fees via USSD: 1. General Operation: ① Dial a designated USSD code using a feature phone: The parking fee management system pre-determines the USSD code; ② The USSD payment integration gateway parses information based on the USSD code and transmits it to the parking fee management system: The USSD payment integration gateway may include mobile network service providers and USSD gateways; ③ The parking fee management system generates a dynamic menu and transmits it to the USSD payment integration gateway; ④ The USSD payment integration gateway receives the dynamic menu from the parking fee management system and returns the dynamic menu to the feature phone. ⑤ Feature phones display dynamic menus; ⑥ Feature phones can select menu options (i.e. interactive items) and perform identity verification.

[0106] 2. Start parking fee calculation operation Such USSD operations include service options input by a feature phone, vehicle information such as license plate number, and identity verification such as SIM card PIN code; When the USSD payment integration gateway receives this type of information, it first performs identity verification. If successful, it creates a unique session ID by combining the device's SIM card number and MAC address and sends it to the parking fee management system. If unsuccessful, it returns the corresponding failure message to the mobile phone. Once the parking fee management system receives the corresponding information, it opens the parking lot fence, starts billing in the background, and sends an SMS notification with the parking session ID and parking information. 3. End parking billing operation: Such operations include service options input on a feature phone, parking session ID, vehicle information such as license plate number, and identity verification such as SIM card PIN code; When the USSD payment integration gateway receives this type of information, it verifies the identity verification and session ID. If the verification is successful, it sends a message to the parking fee management system; if the verification fails, it sends the corresponding feedback message to the mobile phone. The parking fee management system locates the parking information based on the session ID, and returns the billing information and payment confirmation information to the USSD payment integration gateway; The USSD payment integration gateway returns and displays the corresponding parking and parking fee confirmation information (i.e., billing information) to the feature phone. The feature phone displays parking information and a payment confirmation option menu, and replies with the corresponding payment confirmation information (i.e., payment information) to the USSD payment integration gateway. This payment confirmation information includes the session ID and payment password. If the feature phone replies with a non-confirmation payment, the process returns to the billing state, retaining the session ID. The USSD payment integration gateway feeds back the deduction result / operation result to the parking fee management system. The parking fee management system provides the corresponding processing flow.

[0107] The USSD payment integration gateway sends the deduction results to the parking fee management system and feature phones.

[0108] Once the payment is successfully deducted, the parking fee management system will control the gate to open, allowing the vehicle to pass through, and will send an SMS notification with the processing result information (such as parking fee information).

[0109] The parking fee management system will send an SMS notification to your mobile phone if the payment fails.

[0110] Based on the same inventive concept as the foregoing embodiments, the following example illustrates the core link for configuring the USSD payment function provided in this application into a mobile phone's wallet: Core Link Description: 1. Add a wallet service entry point to the main page; clicking it will take you to a secondary page; 2. Has the privacy agreement been approved? Logic for judging privacy agreements: ① Only check if the user has agreed. If they have agreed, skip this part of the logic. If they have refused, return to the parent menu. ②If you try to enter again after being rejected, the judgment logic will pop up again, requiring you to confirm again.

[0111] ③ Whether the privacy agreement pops up is unrelated to situations such as changing cards. Enter the privacy agreement text: 3. Second-level page: When entering, it checks whether the mobile phone number corresponds to the local operator's number. If it does, it displays the local wallet information / menu / USSD code. If it is determined that (multiple card numbers) do not correspond to the local operator's number, it sends the country of the SIM card to the service provider, and the service provider sends the information to the feature phone. When determining the country of origin of a SIM card, follow these steps in order: ①If the SIM card contains a SIM card from a corresponding regional operator, then the information of the corresponding local service provider will be displayed; ②If there is no SIM card of the corresponding regional operator in the SIM, and there are multiple cards, then the country of SIM card 1 will be used; 4. After selecting an option for a service provider's information, you will be redirected to the dialing page. Enter the USSD code. 5. Error message page: ① Error message when the user does not insert a card; ②No network access / Timeout / or the service is not available in this country; Examples of interactive input and output parameters: Upload information format:
