Why can Samsung S5 I9500 mobile phone receive text messages but not send them, but can send multimedia messages? The service number of the SMS center is also correct.

Dear Samsung users:

Based on your description, it is recommended that you try the following methods:

1. It is recommended that you enter Settings - Applications - All-SMS-Clear data.

2. Restart your phone to see if it is a signal problem.

3. Check whether the information center number is correct: Information-Menu key in the lower left corner-Settings-Information Center. The center numbers of each operator and each region are different, please contact the network operator to confirm. "+" must be added before the information center number.

4. Try changing other SIM cards.

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

If you still cannot send and receive text messages through the above methods, please bring your purchase invoice, repair card and machine to a Samsung service center, and engineers will check the machine and handle it.
