I have had my phone since June and I am finding the everytime I leave a wifi area (at home or a friends) my phone won't connect to mobile data (message - disconnected as service is unavaliable). I have to toggle airplane mode on/off to get it to connect.
This happens everywhere and my partners phone (who is also vodafone) has a signal.
Incidently my old Iphone 4 did the same thing!
