Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to recovery from a loss of service in wireless networks. An example method generally includes: in response to a loss of service from a cell of a first radio access technology (RAT) associated with a VPLMN, attempting to camp on a first cell, receiving, from the first cell, a rejection of the camping attempt indicating roaming is not allowed, based on receiving the rejection indicating roaming is not allowed, searching at least one of an home public land mobile network (HPLMN) or registered public land mobile network (RPLMN) for one or more second cells of the first RAT, wherein searching includes refraining from searching at least one other RATs of the HPLMN, and if at least one second cell is detected, attempting to camp on the at least one second cell.
