What I know:
1. If I call a landline, I have no issues
2. When I dial another cell number, a recording comes on that I have to register for "IDD". The IDD stands for International Direct Dial or something close to that.
3. When I take my SIM card out and give it to my buddy with a cheap POS, he can call whoever he wants, cell or landline with no problems.
Items 2 & 3 remove the issue that it is a SIM card issue or a service provider issue and pretty much tells me I have some setting in the phone that is projecting some sort of out-of-region or out of country code issue.
Does anyone have a clue as to where I should start looking or start doing?
I have traveled to China several times on my 8320, and had a similar issue like yours. But my problem was I cant call out period, but able to receive messages. I called RIM and they asked me to update my software, and the problem was fixed
so hopefully this works for you as well. Well, if you have the new operation system then I guess call RIM for some sort of solution?
