The mobile phone number was blacklisted and then released, but the other party could not receive the text message.

Landlord, look at the information report that hasn't been sent yet?

If successful, it means that the other party has received it.

But it was only intercepted by the firewall!

If it is a firewall of third-party software such as Reliance, set it up and look inside.

See if it's in the interception record. If it still doesn't work, uninstall the software and reinstall it.

If it is the firewall that comes with the mobile phone, it has memory function!

It is good to need a mobile phone to restore its factory value!
