Hey Gary,
I haven't had experience with them, but a red flag was raised when I saw their ad a week or so ago. Have a look at their coverage area map for New England.
Note that long distance, texting, voicemail, web, etc. are unlimited (depending on the plan) but they make no mention of roaming charges. Well, no mention UNTIL you look lower at the Value Pocket, a.k.a. pay-per-use services. $0.59 per minute for roaming! If roaming isn't included, you're screwed if you're outside their regional area of Hadley MA to Stratford CT! And, they only have one other regional area in the US currently (in Tx, from San Antonio, down I-35 to the gulf coast).
After writing that last bit, I checked their FAQ. Guess what I found???
Q: What happens if I want to make a call while I am traveling outside of the Pocket coverage area?
A: Pocket customers will be able to roam where we have roaming options available. In order to make roaming calls, you will have to have sufficient funds in your Value Pocket to place or receive a call.
There ya go. Great plan if you're a homebody or a kid in school w/in the coverage area!
