Pros: Good service, competitive rates, decent phones.
Cons: "Charge card" rebates. Doesn't have free or $1 phones anymore. Not sure how the Verizon buy-out will impact them.
Summary: I've never had any problems with Alltel. Back when I first looked for a cellular provider they were the only company to offer family plans with decent rates. I've never had a problem with getting rebates and I've gotten several. All of the people I've dealt with were nice and helpful. They even bent the rules to get me warranty coverage on a phone and on another occasion to get me into a plan that better fit my needs. I was disappointed when the last rebates I got came in the form of charge cards, which meant I had to spend the money. The cards can be a hassle too.
