How does this work. Let's say I am going to Spain for 2 months. I have a GV account with a California area code number. While I'm in Spain, if I use my GV app to make calls to USA numbers 1. Will it be free? 2. Does it have to be GV to GV to be free? 3. Does GV to non-GV numbers work for free or do I have to pay? 3. What about texts? Thanks in advance!
