Why didn't you send a text message 1 day?

1, first confirm whether the mobile phone is in flight mode, and then contact the operator to check whether the mobile phone is down. Through these two, you can basically figure out whether it is a mobile phone or an sm card.

2. If there is something wrong with the mobile phone, first enter the SMS settings to see if there is something wrong with the number of the SMS center. You can call the operator's customer service phone to ask the number of the local SMS center, or you can inquire online. If you still can't send SMS after setting it up, there should be something wrong with the SMS application of your mobile phone.

3. SMS applications can download third-party SMS applications, such as go SMS, Android SMS and so on.

4. If the problem still exists, please try to restore the factory settings. (If the mobile phone root has passed, it may be that the system is incomplete, so it is recommended to brush the machine. )

If the problem still cannot be solved, please take the mobile phone for after-sales inspection and maintenance.
