Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose a method for handling a deregistration procedure of a UE (100) for a disaster roaming service in a wireless network (1000) by the UE (100). The method includes detecting a disaster condition in the wireless network (1000). Further, the method includes triggering a registration procedure with a forbidden PLMN (FPLMN) on a 3GPP access to receive the disaster roaming service in the wireless network (1000) and get registered for the disaster roaming service with the FPLMN (300). Further, the method includes detecting a signal on a non-3GPP access to receive a normal service. Further, the method includes triggering a deregistration procedure with the FPLMN (300) on the 3GPP access to stop receiving the disaster roaming service from the FPLMN (300) in response to detecting the signal on the non-3GPP access to receive the normal service.
