I have been an AT&T customer forever. I have never had a problem on 30-A with coverage. I have also alway's had wonderful customer service with any issue I had with them. I know this is not the case with all, but for me they have been wonderful!
same here. very good coverage + very good service. they helped us adjust to the best plan for us, and billing is easy - nearly the same each month.
I would not switch to Verizon at this point because I know of several friends who have regular problems with coverage (and always have had minor, but frequent problems) - mainly in their own homes, which isn't acceptable in my opinion.
