While i did not have this issue when i transferred my SIM card from my 11 pro max to the 12 pro. I noticed that i could not take photos right from the messaging app not send photos to my Buddy who has android. As the camera icon and the photo app in the messaging app was grayed out.
So i ordered the Verizon SIM card that has 5G on it and activated that at home and after that, mms and the camera icon in the messaging app worked.
