Touch Pro 2 International Data Roaming

[fmesposito]

Looking in the existing threads hasn't revealed a similar issue. I am currently traveling through Europe and can not get International Data to work on my phone but voice roaming is working perfectly. When trying to use data I receive an error that the receiving modem has hung up - I am assuming that this is because the phone is trying to dial #777 which is not how data connections work here. I called Verizon and Activated international roaming and also upgraded to the Global DataPlan.

What settings do I need to use to use data on the phone? I am currently in the Netherlands but had the same problem in France and Brussels and will be in Spain, Italy, Germany and Prauge next. Any tips would be much appreciated.
