Title: CHECKING PUBLIC LAND MOBILE NETWORK (PLMN) AVAILABILITY IN MOBILE DEVICES
Abstract:
Methods for managing data connections on a multi-SIM, multi-standby mobile communication device configured for communications via a first subscription and a second subscription avoid switching service to the second subscription when such a switch may be unsuccessful. Various examples may include performing a manual public land mobile network (PLMN) search using the first subscription, in which one or more available PLMNs for the second subscription are identified in the manual PLMN search. The mobile communication device may obtain an allowed PLMN list for the second subscription, determine whether at least one of the one or more available PLMNs for the second subscription are in the allowed PLMN list, and switch from the first subscription to the second subscription in response to determining that at least one of the one or more available PLMNs for the second subscription are in the allowed PLMN list.
