This disclosure relates to out of service recovery techniques for an accessory device. According to some embodiments, the accessory device may receive cellular communication system selection information from a paired device. The accessory device may store the communication system selection information. At some point, it may be determined that the accessory device has lost cellular communication service. The accessory device may perform a cellular communication service scan utilizing the system selection information received from the paired device along with its own historical information and location based frequency lists.

Intermittent out of service recovery on accessory device

Apparatuses, systems, and methods for user equipment (UE) devices to perform a radio access technology (RAT) upgrade. A UE may initiate a background scan to upgrade RAT while camped on a first system in response to an occurrence of a first condition. The first system may include a first PLMN that operates according a first RAT. The UE may determine a second system operates according to a second RAT that provides upgraded service as compared to the first RAT. The second system may be included in one or more systems found during the background scan. The UE may attempt to register on the second system based on the second PLMN operating according to the second RAT. The first and second PLMNs may each have an associated operator preference and the first PLMN may be preferred over the second PLMN.
