My husband either uses it, or another one that's cheaper. I remember he switched to another pre-paid cell, but I can't recall if it was to or from Tracphone.
I don't know about a yearly plan though, he pays by the month.
TF has an offer on their website that gives you 450 minutes that last for a year plus a phone for $99. They have other plans where you pay by the months, but I like the idea of not having to deal with it for a year.
