At this time, when the mobile phone detects that it has registered to a roaming network, the mobile phone extracts the MCC and MNC of the registered roaming network, and the application uses this parameter. Look up the APN entry for the database. If it is not found, the operation ends; if a matching APN entry is found, the mobile phone application configures the found APN entry as the default configuration parameter of the mobile Internet. At the same time, the network mode is switched to the mode corresponding to this APN entry. The operation ends. Then, when the mobile phone detects that it enters the new roaming network or returns to the non-roaming local network, the mobile phone selects to look up the APN again according to the specific situation or restore the APN to the previously non-roaming configuration state.
