Here's my situation:
I'll be leaving the US for at least a few weeks due to a death in the family. I really want to take my phone with me but don't want to have accidental roaming charges, as I am fairly broke at the moment. For that same reason, I do not want to pay Verizon for international calling either.
I know I'll have fairly widespread access to wi-fi, so I'd like to know if it's possible for me to toggle my phone's cell radio off and use wi-fi only while I'm gone. I'm a little worried that merely toggling "roaming" off may not work right, but anyone that can tell me that's all I need to do, feel free to pipe in and take that issue of my mind.
