4.2.5 EFPLMNwAcT (User controlled PLMN selector with Access Technology)

31.1023GPPCharacteristics of the Universal Subscriber Identity Module (USIM) applicationRelease 17TS

If service n° 20 is "available", this file shall be present.

This EF contains the coding for n PLMNs, where n is at least eight. This information is determined by the user and defines the preferred PLMNs of the user in priority order. The first record indicates the highest priority and the nth record indicates the lowest. The EF also contains the Access Technologies for each PLMN in this list. (see TS 23.122 [31])

– according to TS 24.008 [9].

– Access Technology Identifier:

Coding:

– 2 bytes are used to select the access technology where the meaning of each bit is as follows:

– bit = 1: access technology selected;

– bit = 0: access technology not selected.
