Generally yes. The exact situation depends on the signal system of each country.

Usman, the phone you chose supports GSM and WCDMA at the same time. So it's ok for you to use China Unicom or China Mobile's Simcards. However, I personally think you should use China Unicom's 3G service. The GSM is 2G and it is much slower than 3G when you browse internet pages.
