Can a AT&T Unlocked Iphone 5 be used in China?

I have an unlocked iPhone 5 that is for the At&T network, and I was wondering if it would work in china. Any ideas?

A iPhone that is truly unlocked isn't for any specific network which is why people want to unlock their phones, so that they can go to any carrier they want. I believe AT&T is a GSM network so if the phone came from AT&T and unlocked using iTunes you should be ok. You just need to buy a micro SIM card in china for whatever carrier you choose.

As long as it is unlocked and the network is the same (i.e GSM network) then you can use any carrier sim card in your iPhone.
