Various embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of a first acquisition database to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first and second channels identified in first and second technology lists, respectively, from the first acquisition database, respectively, until either a renewed service connection is acquired or each of the first and second technology lists are exhausted. The first and second technology lists identify channels from first and second radio access technologies. A currently used channel of a second SIM acquired service is first on the first technology list. The processor may perform a full frequency scan to acquire a first renewed service connection for the first SIM in response to determining that each of the first and second technology lists were exhausted.
