Abstract: An electronic device for providing a communication service, and an operating method thereof is provided. Herein, the electronic device may include a communication circuitry, at least one processor, and a memory operatively coupled with the at least one processor to store a Tracking Area Identifier (TAI) list. The memory may include instructions, when executed, causing the at least one processor to run a specified first timer upon detecting an attach failure or a Tracking Area Update (TAU) failure in a first cell, perform cell reselection on a second cell during the first timer runs, determine whether a TAI of the second cell is included in the TAI list, and when the TAI of the second cell is included in the TAI list, forcibly expire the first timer, and transmit an attach request message or a TAU message through the communication circuitry.

Abstract: An electronic device may include a first subscriber identity module (SIM), a second SIM, a communication circuit, a memory, and a processor. According to an embodiment, the memory may store instructions that when executed, cause the processor to set the first SIM to a SIM associated with a data service, and the second SIM to a SIM irrelevant to the data service to determine first capability information associated with a function supported by the electronic device in connection with the first SIM, and second capability information associated with a function supported by the electronic device in connection with the second SIM. The instructions may also cause the processor to transmit the first and second capability information to the network, and to receive allocation of a resource for wireless communication corresponding to each of the first and second SIM from the network, based on the first and the second capability information.
