If you havelocal coverage, you may run the risk of roaming. If you have nationwide service, you should be fine providing AT&T and Cingular have GSM coverage around your area. T-Mobile has spotty coverage in my area too, which is why I didn't sign up for their service, and at the time I looked at T-Mobile, when it was Voicestream, I didn't like their plans because at the time, it was unlimited weekends rather than unlimited nights and weekends, nor did they offer no roaming and long-distance charges on nationwide service. But beware, Cingular and AT&T don't always have good reception in many parts of the country. Those services also have lots of complaints, so you shouldn't rely on their networks for good reception. That's why I don't have them. I live in Gary, IN and I have Verizon Wireless and work great here.
i was looking at the t-mobile coverage map on this site, and it seems to be a bit spotty in my area (Wilkes-Barre, PA). Do u guys think the coverage will be fine or am i taking a major risk? Will other carriers provide much better coverage? Thanks
