Can I send text messages when my mobile phone is hacked?

When the phone is blacklisted by the other party, you can still send messages to the other party. Telephone communication is based on direct communication between the two parties. Once one party blacklists the other party's number, the telephone communication between the two parties will be blocked. The communication of short messages is forwarded through the short message center. Even if the phone number of the other party is hacked, the SMS center will forward the SMS to the other party.

But even if you can send a short message, the other party will not receive the prompt tone and short message notification, and will be automatically blocked in the blacklist by the system, so the other party can't see the content sent, so the short message can be sent, but there is no guarantee that the other party will receive it.
