Well, I guess that confirms it. The Blackjack won't operate on the UMTS
network where I am. By the way I am in Libya, the provider is Libyana.

What is really frustrating is that the provider operates their UMTS
network at a nominal frequency of 1900MHz, and the phone is advertised
as also capable of operating at a nominal frequency of 1900MHz. I had
checked this before I bought the phone. I don't think Samsung or
Cingular can expect the average consumer, like myself, to do anything
more then this.

But evidently even if the nominal operating frequency of the phone and
network match it doesn't mean the actual operating frequency of the
phone and network will match or overlap. **This is an obvious problem
for consumers.** How can the phone manufactures, service providers, and
the organization that defines the UMTS standard not have realized this.
It needs to be corrected.
