Abstract

The invention discloses a number writing system, method and device integrated with an SIM card chip, and relates to the technical field of communication. The number writing system integrated with the SIM card chip comprises a user terminal and an SIM card management end. The user terminal is provided with a communication interface communicated with the chip, and the user terminal is used for acquiring the electronic identification number of the chip through the communication interface and sending the electronic identification number to the SIM card management end; the SIM card management end is used for receiving the electronic identification number, verifying the chip according to the electronic identification number, and returning SIM card data to the user terminal when the chip passes the verification; and the user terminal is also used for receiving the SIM card data from the SIM card management end and writing the SIM card data into the chip through the communication interface. The system does not need to be configured with a temporary seed number, remote number writing can be carried out on the chip by means of the communication function of the user terminal, the number writing process is simplified, and the number writing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a number writing system, method and device integrated with a SIM card chip. Background technique [0002] At present, mainstream SIM cards include traditional plug-in cards and eSIM cards. Among them, eSIM cards are smaller in size and more suitable for complex application scenarios such as humidity, high temperature, corrosion, and vibration, and have developed rapidly in the Internet of Things industry. However, the eSIM card is a physical card, and there are problems in the application process: [0003] 1. The life of the IoT terminal is limited by the life of the card entity. Although the performance of the eSIM card has been greatly improved, in more complex application scenarios, once the physical card is damaged, the terminal will be scrapped. [0004] 2. High cost. The eSIM card is a physical card, which is embedded in the IoT terminal to participate in the chip ...
