I'm going to Germany next month and I want to know if I can use Skype for free on a free wifi network to communicate with my husband back in NY on his droid. I haven't downloaded Skype yet. Is this possible? I have the extended battery on my D2G and cannot get the battery cover off so I don't want to deal with the hassle of buying a SIM card for such a short trip. I think Skype would be perfect if it's free. I assume if I'm in a place with free wifi, that my data usage will also be free. Is that right too? Thanks.
