AT&T go phones are the same, Prepaid may have coverage in a given area, but pay as you go phones won't connect/roam on higher priced networks so their coverage is far less than contract phones. and in some areas no "partner" exists, so roaming doesn't happen.
No agreement = no roaming
"Unlimited" will ALWAYS be constrained by cost, location, and items within the providers control, it does not mean NO physical or artificial barriers.
