For many years I've been perfectly content to take whatever phone a wireless company offered and paid obscene monthly rates whether I barely used the phone or used all my minutes. And I liked it that way. But these days I want to decouple my phone from my carrier. Ideally I'd like a prepaid plan that gives high data usage, but low phone usage that is cheaper than what I'm paying today. And since I'm talking SIM cards, yes, GSM.
What are my options in the USA? I've nosed around and I can't find anything. Prepaid plans here seem to be targeted to older people or young people without credit. Is there perhaps a third option? Postpaid without a contract?
