Hi

I am sorry but it is not possible to adjust the phone in anyways to use 850Mhz band. The phone can work only on the frequencies it has been designed to work on and this is a hardware constraint.

Feel free to ask any question or concern you may have. I will be glad to help you.

Positive Feedback and BONUS are always appreciated.
