What's the matter that the SMS reply hasn't arrived yet?

There are many reasons, so it is suggested that you can deal with them in the following ways:

1. Make sure the signal is normal and close the flight mode.

2. Check whether the SIM card status is normal.

3. Check whether the send key is on and clickable.

4. If you send text messages to multiple people and manually enter numbers, please make sure to use line breaks instead of spaces to separate each number.

5. If you can receive or send SMS, it is recommended to check whether the SMS center is set incorrectly and try again after resetting the SMS center number.
