takeshi's exactly correct. So far I see answers in this thread from Houston, Los Angeles and middle Tennessee; among others - recommending a carrier. None of those answers are relevant or at all useful to you. Coverage where you live, work and often travel to are the only relevant things here. I'm in Plano, like you. I've had AT&T-Cingular-AT&T service for over 15 years now, and am very happy with the coverage I get - and I've heavily traveled all over the country on business also. I see answers talking about better "rural" coverage. The obvious question there is - where do you go very often where its "rural"? If you do go regularly to somewhere "rural", try to find out how the coverage is there - otherwise, its totally irrelevant!
