I am looking to understand what is the best currently available way to use a VOIP service like Skype when roaming outside Verizon's network (this actually isn't going to happen often, but I'd like to be prepared). My understanding of the matter is as follows. The Skype Lite app forces you into using your cellular connection as opposed to Wi-Fi which defeats the purpose of trying to pay less while roaming. Fring and SipDroid both use Wi-Fi and can use your Skype account, I assume if you wanted to call a landline or something you would have to set that up on your Skype account ahead of time. Fring makes it sound like that's all there is to it. SipDroid integrates into your contact list so you don't need to run a separate app, but it sounds like it needs another application PBXes installed. I don't know which is the best option or how exactly either of these work (maybe there's another better option). I'd like to learn more.
