Why can't I send a text message if my mobile phone number is not in arrears?

If the mobile phone can't send SMS, you can try to restart the mobile phone or change the card to check whether the following conditions exist:

First, there is no signal or the mobile phone battery is insufficient;

Second, the mobile phone shields the short message sending function;

Third, the other party's number is blacklisted by SMS;

Fourth, the quantity balance is insufficient;

5. SMS inbox and outbox are full.
