US Coverage Area? What do you think of SpeakOut? | Speak Out in other countries | Consumer forum

My son recently bought me a SpeakOut plan with a Nokia 1100 phone. I don't care for the phone at all. I haven't even charged the thing up. I'm looking to find out what the coverage areas are. I got a brochure with a map of the US with blue areas. You can't tell anything from it. I thought I might find something online that spells out what the coverage area is. Nada. *shrug*

So, anyone with this plan like it? Pros and Cons?
