Anyone else have issues making calls or sending texts after using a WiFi connection on the Razr? I get no reception inside my building at work so I have it connected to our WiFi. When I leave work my signal shows I have 4G connection at full bars, but I can't make calls or send texts. Simply disabling WiFi doesn't work either, I have to restart the phone once outside in order for phone service to work again. It only happens when I'm leaving work so I'm clueless as to what it could be. At home I have no issues with phone service and WiFi, they both seem to work just fine and when I leave my apartment I have no issues using phone service.
