Sony Ericsson Z200 unlocking and roaming

Archived from groups: alt.cellular.ericsson (More info?)

I'm planning on borrowing my uncle's SE Z200 to take to taiwan, unlock it
and use it there.

I see this is advertised as a world phone, anyone know if this is possible?
I brought over a nokia 3595 and it didnt work there, wasnt triband.

currently I'm in Canada, and my uncle's Phone is with the FIDO service here
in Edmonton,

I dont know what Taiwan runs on... but i just wanna know if it'll work in
taiwan and HOW do I unlock it? is it by code like it is with Nokias or do I
need a physical cable?

thanx
