I'll be going to France with a smartphone and want to keep communications as low-priced as possible. Online anyway, I can't figure out what my service provider is talking about! But what I think I'm learning here on Rick Steves' site is that as long as I have a wifi connection and have Skype on my phone, I can call computers in the USA and can also surf the web as much as I like at no extra charge (just as if I were at home). Is there anything else I need to do?? I'm not at all a tech-type when it comes to smartphones. Do I need to have something changed on my phone before I go, or do I just go and go onto the internet once I'm there? Also, I don't want to make or receive any regular phone calls or text messages while I'm there, so do I just leave my phone on "airline mode"?
Any help at all will be greatly appreciated. Thanks.
