Why can't you send text messages? You can send two king cards when you have the phone bill. Why can't the other one?

You can use the King Card to send your mobile phone, so this is not the reason for your mobile phone setting, and you can't send text messages. You can try to restart the mobile phone or change the mobile phone for testing to check whether the following conditions exist:

1. The SMS center number is set incorrectly, please re-enter the correct SMS center number;

2. No signal or low battery;

3. Because the system is busy during the holiday short message sending peak period, it is suggested that you try again later or avoid the sending peak period;

4. The sending format is incorrect. Like giving a landline number.
