Sprint

I have Nextel which is now owned by Sprint.. they have very bad customer service and they tricked my mom into a weird contract. Basically, they gave us minutes to share (a very small amount) per month, and then when those were used up, she had a crapload more minutes. She would always use both up pretty fast and then start talking after 7 instead, and anytime I made a call we'd get an overage fee. `-` The wound up changing our plan three times, and now they charge for all 3. Mom doesn't want to terminate the contract though, so we're stuck with them until November. I've always gotten good reception though and pretty clear voice. They've improved a lot over the past year or so on that.

Verizon is an excellent carrier for service. They come set up phone trucks for my town when hurricanes knock out the phone company and the power for people who don't have good cells, and no one here has anything but good things to say of their service because it works even then. Cingular (now AT&T) also does this but their service isn't as reliable.
