I really wouldn't call this a huge dealbreaker, given they're a budget MVNO. Now Tmo on the other hand has off-network roaming limits that are ridiculously small (like 35mb small) for the entire billing period...and given the scope of their network (read: nonexistent outside of big cities) you're pretty much boned if you live outside a big city.
It wouldn't be if the policy were clear. I was in bandwidth jail through the end of the billing period and could not get an answer about when it would be lifted. At that point, it became impossible to continue with that "service."
