I'm going to Europe and want to use Skype on my droid to contact my husband on his. We want to use Wifi only so it is free. Verizon Wireless won't let me do it. What's going on? I will be the one calling from Germany to him in the US. Is there something I need to download to make this work? Does he need to download anything? Must he be in wifi mode too or it doesn't matter since he's here in the US. Thank for your help.
