I have only been with Verizon. I was with them when they were known as Airtouch. I also sold Verizon for 5 yrs. It is a very good company. And there are good store reps and not so good store reps. Customer care is awesome. I am very happy with Verizon. It is the best coverage and you get what you pay for. I am fortunate to have a company corporate discount, but would still be with them if I didn't. I have never had a bad exp with customer care, a rep in a store yes, but for the most part, has been great. One thing about Verizon, they take very seriously about bad customer service and rudeness.
