What if Samsung can't write short messages?

1. Call or contact the operator to see if the phone is down.

2. Check whether the phone is turned on in flight mode. In flight mode, the mobile phone is in a state of being unable to send and receive signals.

3. Where the signal quality is poor, the short message cannot be sent.

4. If a large number of short messages have been sent before, it is likely that the operator has restricted the short message function, resulting in the failure of sending short messages. You can call customer service for help.
