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.
