Frequency change?

[Guest trendmonster]

Since my wireless carrier runs on 850MHz and 1900MHz frequencies and the MPX supports 1800/1900MHz, is it possible to somehow run the phone on 850/1900MHz?

Thanks in advance.

It's not possible to make it run on the 850 Mhz

you would be better off looking for another phone like the SMT5600
