iPhones are unlocked via Apple who, under instruction from your carrier, types the IMEI of your iPhone into their firmware update servers and pushes to your device a copy of an ‘unlocked firmware’ based on your device’s IMEI.
It depends on whether or not your carrier will allow you to unlock the phone.
Best bet is to give them a ring and find out

You’ll need to jailbreak it in order to unlock it. Without jailbreaking it there is no way to install the unlock code into the root system of the phone. Make sure it’s unlockable. You can go to Settings, General, About. Look at the bottom you’ll see a Modem Firmware. If it’s at 04.26.08 you’re good. If you see anything higher than that, and you can’t unlock right now.
