Western Mass Coverage?

I was wondering about AT&T's coverage in western mass, such as places like amherts and northampton. If i have the local digital advantage, are these areas roaming and will i be charged a roaming rate?

 

AT&T does not offer accounts in Western MA. I know they have a few towers at least around Springfield for their customers traveling through from other areas, probably just near the interstates. If you already have an account from Eastern MA or elsewhere, I see from their website that all of MA is part of the local area, so you could probably roam on Cingular (good coverage here) for free. Best to check AT&T customer service, though.
