My Nokia phone can't send text messages. What is the reason?

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 this is not the case, you can contact the local manual customer service for feedback.
