SMS sending failed, prompting error, no response, how to deal with:

1. Make sure that the SIM card has no arrears/downtime. At that time, the network may be busy, so you can try to restart your mobile phone.

2. Put the mobile phone card on other models for investigation and comparison, or replace it with a new card. If it still doesn't work, confirm whether the phone version is the latest. If there is something wrong with the mobile phone, go to the local service center for testing and handling.

3. Consult the local operator's customer service, confirm the SMS center number and set the information center number.
