Unlocking

[Anonymous]

OK slightly complicated... 

1) I had a two year O2 contract that ended last March (so I've paid off the Iphone).

2) I left O2 and switched to Three at the time, where I moved the number and got a new handset. So the Iphone has just been idle. 

3) I have moved to China!

4) I now need to unlock the Iphone so that I can use it with a Chinese sim card...

Is this possible and how?!

Your only chance is to try the form with the IMEI number of the iPhone and the phone number you used it with on O2.

Then you need a payandgo sim with £20 credit but you have a big problem. Any usage will not be recognised as you are going through a Chinese network and the IMEI will not register on the O2 systems. 

The phone needed to be unlocked in the UK with either a contract sim or payandgo sim. 

I can't see a solution other than shipping the phone to family in the UK and getting them to unlock via a payandgo sim or if any of them are on contract. 

Maybe your best option is selling on eBay....
