Hi, bonafide cheapskate here, and noob. I plan on getting a cheap, used Android phone from ebay and use GV and Groove IP, and my home wi-fi to make/receive calls. I'm confident that will all work out.
What I want to know is what happens when I take my phone with me? I mean, I know I can get somewhere and find another free wifi hotspot, but what about en route? My "local" pub is within walking distance, but it's not right down the street either, so if I initiated a call and started walking, would my call get dropped until I logged on to another wifi? Do I need to log on? (like I said, noob, I've only ever used my home wifi for anything.) What about a car trip? Can my wife sit there and surf the web seamlessly as we pass through different wifi networks (as long as there's always at least one available), or is our connection only as good as our current wifi connection. I'm probably being redundant here, but what about incoming calls? Would I need to log on to a network specifically as I drive around, or would the calls find my phone? I suppose I could have just asked how portable is this system? Thanks.
