Hi, i'm french, i'm using this phone since this summer. Everything was okay for a few months, til i couldn't call in 3G anymore. In despite of the fact that the 3G network is available and the person i want to call has the 3G too, my phone doesn't permit it anymore, like an unauthorised call :-S (no, it's not because of call barring) .
I just want to know if it also happened to somebody else, and how to get the 3G back.
Thanks.
