My Lord, can you send a text message? I can't catch them.

If the message has been sent successfully, but the other party has not received it, it may be that you entered the other party's number incorrectly. You can double-check whether the recipient's number is the other party's.

If there is no error in the number of the receiver, it is recommended to check whether there are sensitive words in the content of the short message, or send the short message to the same number repeatedly, which will lead to being blocked by the operator.

Or the other party's mobile phone is blacklisted at home, and the short message is intercepted and cannot be received, so the other party can check it.

It is also possible that the other party's mobile phone has a third-party security management application to intercept short messages.
