I have Alltel which is now owned by Verizon. They have been pretty good I guess. My kids have Cellar One & like it better. I guess they all have there problems. My Dh's work phone is Cingular I think. He carries both as there are some places where you can't get a signal on one or the other. His phone has lasted almost 10 years & the screen went out so we transferred his number to my old phone with no problems. What ever you get, buy the insurance because it is worth it. Son has lost 1 in lake & it was replaced for $50.00 which isn't bad since it would have cost a lot more to replace. They even upgrade you sometimes with a better phone. Good luck
