Why does it show that my message was sent and the other party could not receive it?

1, hello, the situation you described, I suggest you check whether the following situations exist:

(1) SMS center number is set incorrectly, please re-enter the correct SMS center number;

(2) No signal;

(3) The mobile phone shields the short message sending function;

(4) blacklisted by SMS;

(5) Insufficient quantity balance.

2. If the problem cannot be solved after self-help troubleshooting, it is recommended that you contact local manual customer service to assist in verification and handling.
