Did you read my posts...#22 and #29?

No - there's no registry setting to alter on the mobile RDP. It's how you may have the connection set up from your device to access the cellular network/internet.

Do you have a dataplan? I know you mentioned you got it working via wifi, but I'm starting to notice more and more people are getting cellular and wifi network connection mixed up, or assume it's the same thing, but it's not.

Anyways, check the posts mentioned here, and double check again. Then get back here and we'll assist you when we can.
