I have read all I can about using the Inc overseas and am confused. If the phone is switched to WiFi in a WiFi spot, can you use the phone? I have read that Verizon put some sort of restrictions on it, but I'm not savvy enough to understand it all. My daughter is in the Coast Guard and we both have DInc's. She goes to places like StarBucks in other countries that offers WiFi and we would LOVE to be able to text each other with our phones. Any advice would be greatly appreciated!
