It looks like you only have the Data Plan, did you subscribe to Voice Plan too ?

do u have tmobile.
if u do, the frequency for att and tmobile are different so when you turn on 3g, ull get no service.

so tmobile only has edge

He said when his 3G is turned off = No signal service
When 3G is ON = Signal, really sounds like only Data Plan is subscribed.
Really weird scenario if our aasumption is not correct.

Edit : He should give us more details reqarding whether he is with official carrier and etc before we can narrow it down to the solution.

I got that once. Home+power reset did the trick for me.

Lol what is that reset called? Is it hard or soft reset?

That is a hard reset..LOL, soft reset is just the Slide to turn off.

Have u tried to reset ur network settings? I get a no service message for about 5 secs anytime i switch from 2G to 3G and vice versa. Sounds like ur settings may need to be reset on the phone and if that doesnt help contact Orange.
