I am currently using the German Palm Pre in Hong Kong.

My phone is working fine with the 3HK sim card. However, when I switch the sim card to another company (eg. Smartone-Vodafone). The phone works fine again and I get data service. HOwever, youtube will not work. It just gives an error the can't be played or something.

Does anyone know why? Do I have to reset some setting in order to get youtube to work?

I can surf the web and all with HSDPA service but I can't play youtube videos. I can see that the videos are there but once I click on the video to play I get an error.

When I switch back to the sim I was initially using, youtube works fine.
