Receive and send short messages frequently.

Receiving the same message many times may be a network problem of the mobile phone SIM card. I suggest you:

1. Turn off the phone and restart it.

2. Change the time to receive the attempt again.

3. Send a short message to yourself to see if there will be repeated reception.

4. Try to replace the SIM card of other mobile phones. If it is invalid, it is recommended to contact the SIM card network operator to verify the current network status.

5. If the network status is normal, it is recommended to back up the data in the mobile phone (such as contacts, multimedia files, etc.). ) and restore the phone to the factory settings.

If the problem still exists, it is recommended that you bring the purchase invoice and three-guarantee certificate to your nearest after-sales service center for testing.
