As dropped called could lose me business and moeny, I find Verizon to be the most reliable. Sprint has apparently improved in this area, AT&T amd T-Mobile still need to get it together as they are the worst with dropped calls in this area.
currently i'm wtih fido and thinking of moving to rogers. But as soon as announcements are made about new wireless providers later this year in Canada, i may have to reconsider since rogers painfull gouges customers on data plans
Whoever has the best coverage... Other considerations such as price, policy, etc factor in after that. It's currently at&t but I don't see the point in this poll as it could easily change in the future.
