Got my original T-mobile networked (but had been using a Virgin SIM successfully) Tocco Lite unlocked and walked out of the shop working with '3' SIM card which I checked would make a call - it did. The very next day the message 'Limited Service' displayed on the screen and phone did not work. Tried original Virgin SIM - same thing. Will now only work with a T-Mobile SIM. Yet looking at the 'locks' page on the phone, every one says 'OFF'. Anyone any ideas what's going on?
