The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.
