Have you tried opening the Settings App and going to General>About>Carrier? I know absolutely nothing about carriers outside the US but that might help. Unless that info comes from the SIM itself, in which case I apologize for the unhelpful suggestion. :)

Thread moved to the iPhone Unlock forum.

You'll need to look up the IMSI number (not to be confused with the IMEI) and then cross check the first several numbers with a carrier identifier list. This number cannot be found in the Settings app. I'll post a couple links. After you determine the carrier it's locked to, you can buy a factory unlock as long as one is available for that carrier. Unlocks for AT&T are easy to find and cheap, but unlocks for some of the other carriers are difficult or impossible to find or expensive.

Are you in the U.S. and purchased it from China? If so, you should be aware that if you purchased it on or after January 26th, 2013, it's illegal to unlock it.

If you're in China, have fun unlocking... Actually, do some research first. I have no idea what the law in China is.

My friend also have an iPhone purchased in China working in gevey sim. I think it can't be unlock. There are a lot of carriers like in Japan that it is not unlockable as of the moment.
