Abstract
Embodiments include systems and methods for supporting registration in a fifth generation (5G) new radio (NR) (5GNR) standalone (SA) network by a processor of a multi-subscriber identity module (SIM) wireless device configured with a first subscription and a second subscription. Various embodiments may include determining whether the first subscription received a shared mobile country code (MCC) from the second subscription and the shared MCC is different than an MCC of a home public land mobile network (HPLMN) of the first subscription in response to preforming a full band scan of frequencies supporting the first subscription, and stopping the full band scan by the first subscription and scanning a 5GNR band associated with the shared MCC in response to determining that the first subscription received the shared MCC from the second subscription and the shared MCC is different than the MCC of the HPLMN of the first subscription.
