Well David, I live in a major metropolitan area (San Diego) and work in another major metropolitan area (LA/Orange County). If AT&T wirelss sucks there, I would imagine your experience in Boston ain't gonna be that much different. Believe me I researched this pretty thoroughly, talked with lots of people to get a picture of what their carriers were like, talked with our product manager at work about it and I came to the conclusion that T-Mobile was the way to go, at least for me. It is possible I suppose that AT&T has better coverage in Boston. BTW, I also have the $39.99 plan and have no roaming charges ever. <br><br>
