Abstract: A method includes providing, by at least one processing device, a first set of assignments of international mobile equipment identifiers (IMEIs) to a plurality of subscriber identity modules (SIMs) associated with an electronic device. The method also includes monitoring, by the at least one processing device, each of a plurality of service registration statuses associated with the SIMs for a service registration failure. The method further includes, in response to at least one service registration failure being detected, providing, by the at least one processing device, a second set of assignments of IMEIs to the SIMs. The second set of assignments is different from the first set of assignments.

Abstract: A method includes setting, using at least one processor of an electronic device that includes multiple subscriber identity module (SIM) cards, a maximum Network Address Translation (NAT) interval to be a maximum value among NAT keep-alive intervals associated with the multiple SIM cards. The method also includes triggering, using the at least one processor, a partial call setup from a first SIM card of the multiple SIM cards to a second SIM card of the multiple SIM cards. The method further includes determining, using the at least one processor, whether the electronic device receives the partial call setup. In addition, the method includes, in response to determining that the electronic device receives the partial call setup, setting, using the at least one processor, the NAT keep-alive interval for each of the multiple SIM cards to be equal to the maximum NAT interval.
