Pros: I've found very few dead areas. Reasonably small. More than enough features for someone who just want's a cell phone for emergencies or quick calls. Extremely reasonable cost for above situation.
Cons: Haven't found any yet for my type of usage.
Summary: If you just want to be able to call anywhere when you need to, or be able to be contacted in an emergency, this is the phone. I'd suggest prepaying the $100 in the beginning, then once a year adding the minimum needed to stay a 'gold member' where minutes from previous year roll over. I thought I used the phone a lot last year, yet still had 300 plus minutes to roll over into this year. Even non-techie people like me can use it.
