Anyone combining this with another service like Verizon prepaid to essentially get roaming? I'm not a customer yet, want to, but one thing I'm concerned with is not having roaming. Why not just buy a cheap phone from Verizon and get cell coverage where Sprint doesn't have it? Biggest issue I see is that every service has minutes that expire, which is a joke because you've paid for them. However, if you are always in the same area and can remember to buy more minutes when you go on a trip it could be OK. Thoughts? Without it I'd be worried about things like auto breakdowns.
