A method of handling NAS signaling connection release under mobility management congestion control for MUSIM UE is proposed. A MUSIM UE has established a NAS signaling connection on a first USIM in connected mode. Later on, the MUSIM UE has more important job to be started on the second USIM. The MUSIM UE wishes to initiate a service request procedure by transmitting a service request to the network, to release the NAS signaling connection on the first USIM. However, under the 5GMM / EMM signaling congestion condition with timer T3346 running, the AMF / MME rejects 5GMM / EMM signaling requests from UE.

As a result, the MUSIM UE is able to start the more important job on the second USIM, or to improve user experience on the second USIM.
