Card and phone

I have a question that wheather I can insert a AT&T SIM card in to a China smartphone and use it normally? Or can I insert a China telecom SIM card into a smartphone I bought in AT&T and use it normally ?
Thank you.

It depends if the phone is locked to the original network. The China phone is most likely no locked and will work with the AT&T SIM but the AT&T phone will need to be unlocked before it can be used with the China SIM card.
