Abstract
Techniques for a link budget limited UE to improve communications performance with cellular networks are disclosed. The UE may be associated with subscriptions to multiple carriers and may connect to a cell of a first carrier. The UE may detect that received signal strength from the cell is below a threshold and search for a new cell that may be of a different carrier. The UE may store a PLMN eSIM priority look up table and the search may be based on the look up table. Additionally, the UE may track received signal strength and geographic location in a first data structure that the UE may send to a server. The UE may receive a second data structure from the server that includes received signal strength at geographic locations compiled from a plurality of UEs, including the UE. The UE may also use the second data structure in searches for a new cell.
