I'm currently in Indonesia trying to us Indosat Matrix network. Whenever I insert the SIM card I get the message "Fixed Number Dialing Active" (FW 1.1.4 BL 3.9, 04.04.05_G) and cannot make any calls i.e., no service/signal level. If I use my Hong Kong Sim Card or UK Virgin Sim Card I can make/reveice calls.

I also have the same issue on my wifes iPhone (FW 1.1.3, BL 4.6, 04.03.13_G).

Can anyone help?
