Why do mobile phone text messages always resend?

The reasons why SMS messages are always forwarded may be:

1, network error, this phenomenon will occur where the network signal is poor or when the network is busy.

2. The other party is turned off and the SMS storage is full.

3. China Mobile and China Unicom also send messages to each other, mainly between networks. The other party failed to receive it immediately, but the information platform failed to recognize that the other party had received it.

Sending short messages always fails. Reason:

1, let's see if we can do other networking operations first, and check whether the mobile phone is in arrears and can't send short messages.

2. Check whether the number of the SMS center is correct. Click Information-Advanced-Information Center Number in turn through mobile phone settings to enter, check the comparison with similar local cards or consult the operator to confirm whether the message center number is correct, and make relevant modifications if it is not correct.

3. If there are still problems, please restore the factory settings. Go to other settings through phone settings, click Restore Phone, and then clean up. Warm reminder: Before doing the above operations, remember to back up the important things inside the phone.
