So here's the problem. I have the vz messages app that I use (over WiFi) when I'm out of country and don't have cell service. For a couple weeks it was working perfectly and I was sending and receiving text (sent text were also received by the other person) now as of today I am neither able to send or receive text. I've tried uninstalling the app and reinstalling, tried restarting my phone and nothing seems to work. When I do try to send a text I get a pop up on screen saying " network not available. The message will be sent when the networki s available or over WiFi if you are subscribed to integrated messaging" I never got that message till today When the app stopped working. I have an HTC one phone. Thanks for any help
