This is the reason I can't switch to the EVO from VZW.

"Usage Limitation: Sprint may terminate service if (1) more than 800 minutes, (2) a majority of minutes or (3) a majority of kilobytes in a given month are used while roaming."

I was booted from At&t's network because of this. I had an iPhone for all of 3 weeks before they cut me off. I failed to read the "fine print".

As far I know, Verizon doesn't not have this clause in their contract. Besides, I have never been able to find an area to roam in. I might be paying more per month, but at least I can depend on not getting shut down.
