    Abstract: A method for dynamically switching a data subscription in a multi subscriber identity module (SIM) multi standby (MSMS) mobile communication device includes: in response to determining that signal energy for a first subscription detected during a background public land mobile network (BPLMN) search remains greater than or equal to a threshold signal energy value during a first specified time period of a first timer, reducing a second specified time period of a second timer for a second subscription; determining whether any data communication activity occurs on the second subscription during the second specified time period; in response to determining that no data communication activity occurs on the second subscription during the second specified time period, performing a dedicated data subscription (DDS) switch from a second subscription to the first subscription.
