How to unlock an iphone 4s under contract?

Please I seriously need an answer and that's for answering…

You can unlock your iphone by calling your carrier of course but since you are still in contract there might be fees to be paid. Unlocking your phone will void your warranty however if you really want to do it by yourself, there are safe and easy way of doing it. I unlocked my phone recently and don't have problems with it. I use this site and i find it useful, hope this can help you aswell.
