I'm in singapore.Recently I changed my SIM with an one supporting 3G from the service provider Singtel. But I found it can receive calls, but can not call out. It shows the call is connected, but,neither I can hear anything nor the receiver does, i.e. I can't anything during calling, even the dialing tone. This SIM card and my phone can work on another phone and SIM card respectively.
I've tried 2003 and wm5 ROMs, the problem is still there. Since I havn't smartphone2002 anymore, don't know if it works.
Any idea to solve this?
I assume U R trying to put UMTS sim into MPx200. Correct me if wrong. Since MPx200 doesn't have UMTS, it probably won't work, as, it doesn't.
