Problems solved by technology

A physical SIM card is a SIM card that can only be embedded in a terminal and bound to a terminal at a certain moment, and once the physical SIM card is lost, the user cannot communicate, so the user is absolutely dependent on the physical SIM card and brings great inconvenience to the user. Great inconvenience, especially with the development of society and economy, the number of Chinese outbound tourists and business people is increasing rapidly, and the rate of users using mobile phones to surf the Internet when they go abroad is also increasing, and the cost of international roaming services is very high
In order to avoid high international roaming charges, users either look for free WIFI, or buy a local SIM card, but free WIFI needs to be available in certain fixed locations, and it is troublesome to buy a local card to replace, which brings a lot of inconvenience to the user's life abroad

Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The invention provides a method for realizing a virtual SIM card, such as figure 1 shown, including:

[0047] S1. Establish a communication connection between the user terminal and the virtual SIM card operation server.

[0048] Since information such as the IMSI and authentication data of the virtual SIM card needs to be purchased from the virtual SIM card operation server, it is first necessary to establish a communication connection between the user terminal and the virtual SIM card operation server, so as to facilitate the establishment of information interaction between the ...

Abstract

The invention provides a method and a system for implementing a virtual SIM (Subscriber Identity Module) card and an intelligent terminal. The method comprises the following steps that: a communication connection is established between a user terminal and a virtual SIM card operation server side; an operation server returns an IMSI (International Mobile Subscriber Identity) and authentication information of a virtual SIM card which corresponds to order information to the user terminal according to the received order information of the virtual SIM card purchased by the user terminal; the user terminal downloads the IMSI and the authentication information returned by the operation server locally, and activates a preset virtual SIM card module according to the IMSI and the authentication information; and the virtual SIM card module accesses a network through a MODEM interface module. A user can select different roaming plans according to the type of an SIM card in a mobile phone of the user and access the network conveniently; the trouble in finding free WIFI (Wireless Fidelity) or replacing a local SIM card is eliminated; and expensive roaming charges due to use of a domestic network abroad or remotely can be avoided.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method, system and intelligent terminal for realizing a virtual SIM card. Background technique [0002] The traditional SIM card is a physical SIM card, which is generally used in the terminal. The terminal reads the information of the physical SIM card and performs relevant authentication. After the authentication is passed, normal communication can begin. A physical SIM card is a SIM card that can only be embedded in a terminal and bound to a terminal at a certain moment, and once the physical SIM card is lost, the user cannot communicate, so the user is absolutely dependent on the physical SIM card and brings great inconvenience to the user. It is a big inconvenience, especially with the development of society and economy, the number of Chinese outbound tourists and businessmen is increasing rapidly, and the rate of users using mobile phones to surf the Intern...
