AT&T 3G 71234 D

Base on community post:

The 71324 is the SKU for the AT&T latest UICC. The 2022 is the Vendor and Version number.

Some cards the vendor numbers are

  2 - G&D
  3 - Gemalto
  4 - Oberthur

Usually user will get CME ERROR 13 (sim failure), rather than CME ERROR 10 (sim not inserted) when 3G SIM not working.
