The invention relates to system enablers for multi-sim devices. Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level. 本公开涉及用于多SIM设备的系统启用器。本文公开了用于用户装备设备(UE)执行用于增强多SIM设备诸如UE 106的方法的装置、系统和方法。网络可例如基于来自MU-SIM设备的能力指示来增加已知MU-SIM设备的寻呼重试。该指示可经由NAS注册请求、RRC能力程序和/或RRC UE辅助程序。另外，网络可包括对该UE的寻呼优先级
