Patent ID: 11228998

Abstract:
A communication device, method and computer program product enable increased functionality using multiple subscriber identity modules (SIMs). The communication device is camped on a first network node of a first subset of network nodes of a first public land mobile network (PLMN) as one home PLMN using a first SIM. The communication device is camped on a second network node of a second subset of network nodes of a second PLMN as another home PLMN using a second SIM. The communication device monitors communication performance and level of quality of service available from the second PLMN while connected using the second SIM. In response to determining that the communication performance and/or the level of quality of service would be improved, the communication device triggers a radio frequency (RF) front end of the communication device to scan for, acquire, and register to one of the first subset of network nodes using the second SIM.
