Your carrier, (AT&T;, Verizon, etc.) should be able to unlock it and put the appropriate sim in it.

It is locked. I tried using it in Brazil and didnt work there. Just in the US and T-Mobile unless you unblock it somewhere else.

I am not sure. I researched it and I am under the impression that carrier unlocked phones still have software specific to the carrier, where the factory unlock does not tie to a specific carrier. I am not sure that I understand this fully and do not know if it can be used out of the country. Sorry!

Yes, it is unlocked. My brother is using it in India, so you should be able to use in other countries too.

the Chinese number is on a sticker that comes with the card. I didn't activate mine till I got to China. That is what the instructions told me to do. I did not try to use mine in USA

The phone that I received is LOCKED and is unusable except on AT&T; networks in the USA. I have tried unsuccessfully to log into the O2 network with a working O2 SIM card here in the UK. I cannot recommend buying it.

The one I bought DID NOT COME UNLOCKED... I had to have it unlocked when I got it.

it's not unlock. You have to call t-mobile customer service in order to unlock it. It can be unlock here in the US or Jamaica. Just remember tat a fee will be applied. It could be used to any country's provider that carries sim

I bought this phone and discover that google store was not allowed at all! Chinese model and I had to cheat to use google store and co. And then the phone stopped working after 10 months! I am very angry about this phone, it was a real mistake to buy this model.

What I would suggest is talk to your provider to make sure you can have it unlocked and use it at the place where you use it.

The phone is not unlocked but you can unlock it and use it for your country since it is a GSM phone. You will review the phone locked. You will have to unlock it yourself.

It is unlocked, it is quad band, and it takes a SIM card, so the only thing you'll need to do is insert your SIM card from China Mobile or similar and it should work.

Hello! I don't know what you mean with "open phone", a unlocked phone is a phone that can work with any company in every place of the world. A phone purchased in a AT&T; store only works with AT&T; mobile system and within USA (that is a locked phone). I bought a Samsung S4 unlocked (international version) and I'm using it in Venezuela.. so I highly recommend you to buy a unlocked phone. It should works perfectly in China.

Yes, it is an International Version. Its a plug and play kind of mobile. No need of unlocking as such. I bought it and I am using well in my country without unlocking. Its working!!
