There is no problem with the number of the information center, but why can't some mobile phones send messages?

You can set a reply report when sending a short message, which will tell you whether the other party successfully received it;

If the report is successful and the other party does not receive it, it may be that the other party has a SMS firewall, or the other party's SMS center has locked the other party's number;

If the report is unsuccessful, contact customer service, which is a data problem of the operator.
