For certain operators, the LMU can auto-populate the APN, username and password settings based on the
Mobile Country Code (MCC) and the Mobile Network Code (MNC) of the SIM. Upon inserting a new SIM
the APN, username and password will switch to the new SIM card's defaults if the MCC and MNC values
change. The current list of supported MCC and MNC combinations are:
AT&T – formerly AT&T Wireless or Cingular Blue (MCC 310, MNC 38)
