What if I can't send a text message? It can be used normally, but the SMS can't be sent out.

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:

1. Whether the SMS center number is set correctly, please enter the correct SMS center number;

2. No signal or low battery;

3. The mobile phone shields the short message sending function;

4. The other party's number is blacklisted;

5. Insufficient quantity balance;

6. SMS inbox and outbox are full.

If not, you can contact online customer service through "China Mobile 10086" WeChat official account, or directly call the hotline manual station 10086 to handle the problem.
