I'm
supposed to have a QualComm (according to some @ my company), but I refuse to, because it is not worth $13 or so a month.
I recently switched to Straight Talk cellular, because it is very cheap to have; only $30 a month gives me 1,000 minutes (that's 16 2/3 hours!) + 1,000 text messages + 20mB of data.
The box the phone comes in, and even the customer service people say you don't get rollover minutes - but I always have gotten them; rollover on EVERYTHING, so if I have an unusually busy month, I'm covered w/ the rollover minutes. One month, I was at 25 hours available.
They also have a totally unlimited minutes plan for $45 - for the blabbermouths!
The system they use is Verizon, so it is the best available.
BTW: Straight Talk is only available at Wal Mart.
