Since you are in Asia I am assuming you are using the radio in GSM mode.

That said, if you go to Connections and pick Verizon Wireless there should be three options in the modem tab.
"Auto Pick", "Verizon Wireless" and "VZW Embedded GSM".
In your case it would be best to select "VZW Embedded GSM", which would dial using the GSM modem.

The fact that your phone is attempting to dial #777, tells me it is trying to dial into CDMA data. This obviously won't work as you are using a GSM network.

If you don't have the proper connections setup, then you are going to have to go back to stock to connect. Be aware that flashing your phone while roaming is generally a bad idea. I have heard of people not being able to use their phone after a flash when roaming until they came back home.
