How to Unlock an iPhone?
Please take backup of your iTunes before you start (for safety reasons of losing data)
NOTE: USING THE SAME PROVIDER SIM CARD (THE PHONE IS LOCKED TO) TO DO RESTORE WORKS BEST FOR THIS PROCESS! You can use a DIFFERENT carrier GSM sim card as well.
Make sure you are using the most UPDATED version of Itunes 12.3.2 or whatever is current version.
Make sure you update your iphone software to 9.2.1 or newest software available during restore for your phone model.
