Abstract

The invention discloses a network connection method, an SIM card, a system, a terminal and a medium. The method comprises the following steps: acquiring a network code for identification; if the network code is not matched with the network code in the last connection, performing networking operation according to an independent transmission protocol; and after exit roaming, enabling the report of exit roaming information preferentially to use an independent transmission protocol, so that the cost of an OTA report channel is reduced, the reliability is high, the error-tolerant rate is high, thesystem stability can be improved, an operator system does not need to be docked, and the use cost is further reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a network connection method, a SIM card, a system, a terminal and a medium. Background technique [0002] With the improvement of people's living standards, outbound travel is becoming more and more popular. When traveling abroad, due to the different standards of operators in various countries or the lack of user agreements between operators, users will not be able to use data traffic services directly after going abroad. [0003] In the related technology, the overseas roaming data traffic passes through a Subscriber Identity Module (SIM) card that can perform global roaming and switch Profiles through the air channel (Overthe Air, OTA), and remotely and over-the-air Profile distribution and distribution based on the OTA channel. Switch, manage and recycle, and provide data roaming services for outbound users. [0004] At present, when roaming abroad, the OTA SIM card of t...
