I recently arrived in Hong Kong for a vacation, hoping to use a local sim in m phone while there. It picks up the sim correctly (a pccw sim if that matters), however I cannot dial out as all calls instantly fail.

I've noticed a few things on the net saying to go into airplane then switch call id on and off, which didn't work. I also changed the regional settings to HK so the number is formatted correctly without any luck.

Does anyone have any ideas? It almost sounds like I need iworld, but that ended with fw 1.1.3....not to mention fw 2.2.1 is shared with the 3G which is sold in HK.

I'm sure its something simple but I'm stumped atm.
