A method for timer T adjustment due to disaster roaming occurrence, and an apparatus for supporting same. A user equipment (UE) determines that a disaster condition applies to a home public land mobile network (HPLMN). Upon selecting a disaster roaming PLMN, the UE performs a first registration procedure for disaster roaming services on the disaster roaming PLMN, and periodically attempts to obtain service on the HPLMN based on a timer T with a first value. Upon selecting a Visited PLMN (VPLMN), the UE performs a second registration procedure on the VPLMN, and periodically attempts to obtain service on the HPLMN based on a timer T with a second value.
