I have an unlocked Samsung Blackjack phone which I have taken overseas
to Africa.

I have installed a SIM card from a local provider and am using the
phone with this provider's network. I can make phone calls and access
the provider's GPRS system with no problems. However, I am unable to
connect to their UMTS (ie: 3G) system. (The provider does indeed have a
UMTS system installed and functioning.)

In the header bar at the top of the phone's screen I only get a "G",
indicating GPRS connection capability. I do not get a "3G".

Any suggestions on how to get this phone to connect to a UMTS system
other then Cingular's would be most appreciated.
