this is a known problem with the 6800.

nokia made two version of the 6800, one was meant for the U.S market, and one for the european market (the european version is also for the rest of the world).
the u.s version works with 850/1900 MHz frequency, and the european version works with 900/1800 MHz frequency.

you can't get signal, because the phone (u.s version) and the network in dubai use diffrent frequencies, and phisically they can't communicate.

maybe you can get a european firmware and flash it to yours any ideas on this guys or is it restricted hardware wise?

[Yotamz]

frequency is in the hardware, a firmware flash won't help.

i don't understand why nokia did this, this is the only model that has two versions that are different in hardware, and both have the same name (6800)..
