Hi guys! I bought an AT&T HTC One X in the US (naturally), and brought it to Europe. The phone works alright, mostly, but when I connect to the internet via the network connection and not the WiFi the connection works fine for a while and then suddenly stops working. It usually stops working after about 5 or 10 minutes, and the only way to get it to connect again is to restart the device - not even turning the connection off and back on works. Connecting to a Wifi works fine even after the network connection has stopped working. Any ideas what the cause may be? Thanks!
