Abstract

Aspects of the present disclosure includes a method of performing enhanced auto-selection in a UE including initiating the UE having at least a first subscriber identify module (SIM) card and a second SIM card, obtaining a current ICCID associated with the first SIM card, obtaining, from a cache of the UE, a previous ICCID used in a previous connection to a previously identified carrier, determining whether the current ICCID matches the previous ICCID, in response to determining that the current ICCID does not match the previous ICCID, creating a new card information using data stored in the first SIM card, obtaining one or more selection policies, identifying a carrier based on the one or more selection policies, and connecting to the identified carrier using data stored in the second SIM card associated with the identified carrier.
