Can Samsung Curved Screen s7 SMS be sent? What happened?

1. Edit a long short message on your mobile phone and give yourself a try.

2. Try to change another SIM card to receive SMS.

3. Back up the data in the mobile phone (contacts, text messages, pictures, etc.). ), and then try to restore the factory settings.

If all the above methods are ineffective, there may be something wrong with the internal program. I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung service center for engineers to check the machine.
