Why can't the mobile phone receive any messages, and Samsung s5 can't receive any messages?

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

2. Find [Settings]-[Application Management]-[Information]-[Input], clear all data and try again.

3. Try to replace other SIM cards to see if it is because of the mobile phone card.

4. Check whether the mobile phone is equipped with third-party security software such as security guards, intercept the short message, uninstall and try again.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and try to restore the factory settings.

If the above methods still fail, it is suggested that the mobile phone be sent to Samsung's professional service center, and the machine will be inspected and processed by engineers.
