Gsm 850 In A Gsm 900 Country

I don't know the exact frequency bands; maybe there is some overlap at the edges, or the tuning is just tweaked sideways a bit. I'd be surprised though, as I imagine the band allocations are in the range of a few MHz or so, rather than 50 or more. Are there two offset duplex bands, like ordinary radio with repeaters?

The phone has also GSM1800. So all you need is a 900/1800 network with not every station having 1800 to have the phone work "sometimes".
