Hello, I have Visible and I am traveling to London. I understand that Visible does not work in Europe and I need to purchase an international SIM card for service. What I need to know is whether my phone will work over airport Wifi, meaning I can buy a SIM card when I arrive in London, or if it will stop working altogether when I arrive in Europe, meaning I should purchase an international SIM card before I go on my trip.
I want to reiterate the above Answer just to assist others searching on this same issue. According to Visible Tech Support (who I just hung up with to confirm this) "as long as you have FIRST ENABLED WiFi calling while in the U.S., it will work in Europe". So the important point is you must first turn on your WiFi Calling in the States, otherwise it will not work. (This was 100% contrary to what the Visible CHAT rep had stated, which is why I insisted on a call back from Visible. I also suggested to him that they re-educate their Chat people as well as add this very important distinction to their FAQ's on International Use)
