iMessage not working

[RobK]

Since moving from ID to o2 none of my TXT msgs go as iMessage instead they go as a Green SMS, the phone is connected to Wifi and data.
I have turned off the option to send as SMS but it still sends anyway...
iPhone 12 pro.
Any ideas?

This walks through all the imessage settings and setup.
