4.2.58 EFPNN (PLMN Network Name)
31.1023GPPCharacteristics of the Universal Subscriber Identity Module (USIM) applicationRelease 17TS
If service n°45 is "available", this file shall be present.
This EF contains the full and short form versions of the network name for the registered PLMN. The ME shall use these versions in place of its own versions of the network name for the PLMN (stored in the ME’s memory list), and also in place of the versions of the network name received when registered to the PLMN, as defined by TS 24.008 [9].
This file may also contain PLMN additional information to be displayed to the user during the Manual Network Selection procedures as defined in TS 23.122 [31].
If the UE is registered in NG-RAN and EFOPL5G is not present, or if the UE is registered in other technologies and EFOPL is not present, then the first record in this EF is used for the default network name when registered in the HPLMN (if the EHPLMN list is not present or is empty) or an EHPLMN (if the EHPLMN list is present).
