Xr can't send text messages.

If your mobile phone can't send short messages, you can try to restart or change your mobile phone for testing to see if the following conditions exist:

1. SMS center number is not set correctly. Please re-enter the correct SMS center number.

Second, the number balance is insufficient, and try again after recharging the phone bill;

3. The SMS inbox and outbox are full. Delete unnecessary messages and try again.

4. Blacklisted by SMS;

5. The short message sending time exceeds 24 hours;

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

Seven, send the format is not correct, such as sending SMS to PHS users, the number should be added before the area code;

Eight, there is no signal or the battery of the mobile phone is insufficient. Move to an open place or try again after enough power;

9. The system is busy due to the peak of sending short messages during holidays. It is recommended that you try again later or avoid sending peak hours.

If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
