Very agitated.

This is NOT A BUG THAT APPLE CAN FIX. It is a problem with YOUR PHONE. If it was a bug you would see hundreds of thousands of posts about it.

You might be misinformed as there are millions of users sending messages without any problem at all. It seems the issue may be a problem with your device/carrier. If this was a bug, then not only would you see it here, but would also be the top story of every news program.

For a resolution to your problem, start with the link provided by IdrisSeabright and describe exactly what you tried in that support article and what has not worked. That is the way you resolve issues on this support site. Also let us know if you are using a VPN.

SMS (green) is a carrier feature. If you're having trouble with SMS, you need to contact your carrier. If you're having trouble with iMessage (blue), please explain the exact error message.

And, yeah, Apple is not here.

There is NO APPLE here in these user to user technical forums, as outlined in the TOS you signed up for.
