Samsung s5 Telecom Edition failed to send SMS, and finally failed to send it. The signal was full, but it only succeeded once. You can receive text messages and make phone calls.

According to your description, I suggest you try the following methods:

1. I suggest you go to Settings-Applications-Manage Applications-All-SMS-Clear Data.

2. Restart the phone to see if there is a signal problem.

3. Check whether the number of the information center is correct: Information-Menu button in the lower left corner-Settings-Information Center. The number of centers in different operators and regions is different. Please contact the network operator for confirmation. The number of the information center must be preceded by "+".

4. Try to replace another SIM card.

5. It is recommended that you try to upgrade the firmware. (Settings-System-About Equipment-System Update)

If you still can't send and receive SMS through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung Service Center, and the engineer will check and handle the machine.
