I'm in Miami Florida, no phone network access, autoselect has picked AT&T, I have signal strength but there is a small R above the triangle, I can't text or phone. On my ID account I have roaming, international, and premium enabled, I also have a large increased credit cap and lots of text, voice and data available. On my Android device I have roaming enabled. I can't think of what else to try?

Small R next to the triangle means that you are correctly connected while Roaming. It's a good thing to see R in there while abroad.
My suggestion, not sure if this will help but it's it's worth to try.
Maybe editing number of there person you trying to text and add +44 instead of 0 would help. You know like when you have 0799.... Change it to +44799… (in case if you trying to call British number).
