Well, if so, that's a good thing. T-Mobile desperately needs AT&T roaming in Eastern NC. There's a huge dead zone along highway 64, and entire numerous entire towns with no coverage. Most of these areas don't have a huge population but it makes using T-Mobile a difficult choice for anyone who travels in the state. I'm not saying T-Mobile should build native coverage since there I doubt they could ever get a return on the investment, due to low population, but they should at least be able to roam for people who travel through these areas a few times per year.

I have considered switching to T-Mobile a few times, but the lack of coverage in areas that VZW and AT&T cover has always concerned me. Sprint also lacks coverage in many of T-Mobile's dead spots, but at least they can roam on VZW (or maybe USCC... not sure who they are roaming on at the moment).
