Because the coverage at my apartment is pretty much non-existent, I have to force my phone to roam every day when I turn it on. And no, it is not smart enough to roam on it's own because, for some reason, it thinks 0 bars on Sprint's network is fine, even though I cannot make or receive calls at 0 bars. So I'm on the SERO 500 plan and it says that Unlimited Roaming is included. Is it really unlimited? I've read something saying that Sprint will take action if you roam "too much", even if your plan includes unlimited roaming. Is this true? How much is "too much" and what happens if you do roam "too much"? I don't really care that I am roaming -- other than the fact that I have to tell my phone to roam, which is so stupid -- but should I be concerned that all of my minutes, texts, and data usage are on Verizon?
