1. A method for performing communication by an electronic device, the method comprising:transmitting, by the electronic device, a first connection request message for a service connection to an external device;
receiving a first connection reject message based on the first connection request message, when the electronic device is not registered for the service connection;
abstaining, by the electronic device, from retransmission of a second connection request message to the external device based on the connection reject message until a first time elapses, wherein the first time elapsing is related to a state in which the service connection is available;
performing, when the first time elapses, the retransmission of the second connection request message to the external device;
receiving a second connection reject message based on the retransmission of the second connection request message, when the electronic device is not registered for the service connection;
comparing a first rejection reason for the first connection reject message with a second rejection reason for the second connection reject message;
based on identifying the first rejection reason for the second connection reject message being identical to the second rejection reason for the second connection reject message, setting a second time to be less than the first time that elapsed before,
performing, when the second time set to be less than the first time that elapsed before, retransmission of a third connection request message to the external device; and
communicating with the external device based on the retransmission of the third connection request message when the electronic device is registered for the service connection based on the second connection request message;
wherein the first connection request message includes at least one of subscriber identification information or access point name (APN) information.
