The phone has been turned off. How to fix the short message?

According to your description, if your mobile phone can't send SMS, please try the following methods:

1. Check the information center number: Information-Menu-Settings-Information Center (please contact your local network operator for the information center number).

2. You can receive SMS normally, maybe there is something wrong with the SMS program. You can go to Settings-Application Management-All Information-Clear Data to see if it can be solved.

3. If you still can't send text messages, you can try another SIM card.

4. If you still can't send SMS after the above operation, you can restart your phone and try. If it still doesn't work, you can back up the data and restore the factory settings.

If it still doesn't work after operation, it is recommended that you take your mobile phone to the nearest Samsung service center for inspection and maintenance. For the specific location, I suggest you apply for "booking to the store" in Samsung official website to enjoy priority maintenance service:/Pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
