Failure to send SMS may be caused by the following situations: 1. The SMS center number is set incorrectly; 2. No signal or low battery; 3.

The mobile phone shields the short message sending function; 7. Blacklisted by SMS; 8. The quantity balance is insufficient. See what causes it, and then solve it in a targeted way.
