What's the best cellular service provider?

I've used virgin mobile, verizon, t mobile, sprint and tracfone services. And out of all the best one was verizon. The reception and service NEVER went out. I had no problems with the bill, but I had to let it go because of other bills.

i have used aircel,airtel,vodafone out of these i prefer airtel because the signal is very good wherever you travel the signal responds well.eventhough its quite expensive the network provides good offers like night talk at a lesser charge for two numbers.right now am using airtel only.

here in india i think airtel is the best service provider the network coverage is excellent in such a large country with with more rural places and forests the network coverage is good even in such places the clarity of calls is clear and the fares are just normal as the other services here cellone has also got good deals but the company lacks the customer support and the service is bad apart from the quality of the provider

Well I use AT&T although I can't say its been perfect... but it is very reliable! =D
