Am trying to get Google Voice set up in anticipation of a trip to Mexico in a couple of weeks. So far have a GV account, and can make GV calls from my Droid easily. There's one problem though. When I do that my Droid is actually placing a call using my Verizon connection. That's fine here in the US, but I want to place calls using WiFi ONLY when I am in Mexico. Is this something that GV can do?
Note: I tested this by turning on "Airplane Mode" in my Droid, but then separately turning WiFi back on. It then connects to my home wireless and I can browse the web, but not make or receive calls directly. This is the situation I expect in Mexico. Then when I try to place a call with GV, it tells me I have to turn off "Airplane Mode" first. In other words, it seems unable to make the GV call without using my cell phone carrier.
