My BB is through work and since I don't usually need coverage in another country it wouldn't pay to get it. They'll pay the charges if there are any, I'd just like to know beforehand to give the IT folks a heads up.
I do have the unlimited data, and I was in Texas during Hurricane Rita and 2-way worked fine. The main thing for me will be the phone. I can check email from my laptop while I'm there if I have to.
