Unfortunatly not. Since the frequency depends soley on the hardware, there is no way to change or add to the frequency range of a cell phone.

Yep, jamrbutl is right. 850 and 1900 frequencies are mainly used in the US. 900 and 1800 Mhz are used in the rest of the world. You should have bought a phone that supports 900/1800/1900 Mhz not 850/1800/1900.
