It definitely works well with AT&T; here. It should work just the same in Canada, if your AT&T; plan includes coverage in Canada. Coverage should be fine, if your AT&T; international calling plan includes China. If you're unsure if the phone itself, will work, then you can contact Lenovo in China. Lenovo here in the US won't know, since they don't sell or support any Lenovo phones, being that they're only sold as unlocked devices outside the country. They could only assist you, if it was a product that a US carrier offered with their service.

My carrier it AT&T and it worked overseas though you may need a chip from them and it will cost more. I don't know who your carrier is and don't know if overseas also includes China. I was only asking about Europe and the middle east. Ask your carrier

Well I'm not sure. But what I can say is : I'm using this phone outside the United States with another carrier and it works great! Right off the ball it connected to the service. So technically it should. I hope this helps you to decide

I used it only in USA and has worked fine. Since it is an unlocked device,I simply inserted my carrier's(AT&T;) SIM card and it started working.I am not sure but I think it should work anywhere.

Asia has a lot of countries and each country sets its own operational rules. If the carrier uses 1800/900 MHz band, it will work. It works well under China Mobile's network, the only one I tested.

It should because it's GSM unlocked. It will work on any GSM network. GSM was the global network introduced first by AT&T. Check to see if you have a GSM network provider.

It is unlocked, it will work all over the world. In US it works with AT&T and T-mobile. If you use other carrier please check with them. Keep in mind with this phone you will need a MINI / MICRO SIM card.
