Abstract
The apparatus determines whether a subscriber identification module (SIM) card is a first network SIM card or a second network SIM card. The apparatus performs an unlock sequence for personalization based on a subscriber permanent identifier (SUPI) if the SIM card is determined to be a first network SIM card. The unlock sequence may include determining whether a SUPI of the first network SIM card matches with a SUPI stored in a secure file system (SFS) at the UE. The unlock sequence may further include initializing the UE to a network if the SUPI of the first network SIM card matches with the SUPI stored in the SFS at the UE.
