I swear by T-Mobile. It's the only nationwide GSM carrier in the US, which means that I could get as good a signal in New Zealand as here (Sedona, AZ).

Verizon was the ONLY cell company that services my house. I've tried three different others but they all die about a 1/2 mile from the house. That said, if I didn't absolutely need to have a cell phone - I wouldn't keep Verizon for a minute. Their customer service personnel are abrasive and ignorant. Their billing practices are abysmal and their equipment unreliable.
