Post that code here.
Keep in mind also that the UMA service is not guaranteed to work on every single wireless router or network you can connect to. The error code will give us a place to start troubleshooting, though.
Dave, here's the messages that i got under UMA section when i put my tmobile US sim card in the Orange french 8320:
Error Code: blank
Status: ISP or T-Mobile Network error
Reg. UNC Address: hbsc.mobile.orangefrance.fr:14001
Registration: red x
Authentication: red x
Serving UNC: hbsc.mobile.orangefrance.fr:14001
Security Gateway IP: sgw.mobile.orange.fr
I hope this will help.
Now i have another problem which is very wierd as i spent about 2 hours with a tmobile rep just now and which is:
Using the same WIFI network and the same tmobile 8320 device on 2 different US Tmobile sim card, i.e. 2 lines on my account. One registers UMA and works perfectly and the other doesnt, and they cant figure out why. I will get you the error under diagnostic once i exchange the SIM card again.
