With the development of mobile terminal technology, data services have been key services of the mobile terminal industry. The most critical for determining whether the data service of the operator can be used is the information setting of the APN (which is called Access Point Name, data network Access node). The mobile terminal can use the data service provided by the operator only after the valid APN data information is correctly configured.
At present, with the increasing number of operators, especially virtual operators, making their own requirements for APN, a mobile terminal often needs to establish new APN data information in order to be able to use data services provided by the virtual operators.
