When you bought your Nokia Lumia 520 or Lumia 1020, it was likely on contract with your wireless carrier. When you’re done with your contract, unlocking the phone is a simple process as long as you have an eligible phone and all of your information at the ready. Unlocking is useful if you want to bring your smartphone to a new carrier.

Your phone is eligible if:
[listNum]■All monthly bills, installments, and other monetary dues have been paid to the wireless carrier in full and there is no outstanding amount on the device whatsoever.

■The phone is still locked with the wireless carrier, is in use, and is active.
■The phone has not been reported stolen or lost by the owner.
■The IMEI number of the phone has not been blacklisted or blocked.
■The phone has not been involved in any criminal or fraudulent activity.
■The locking threshold duration with the current wireless carrier (1 year or more for prepaid subscription; 60 days or more for postpaid subscription) has been reached.
[/listNum]

If you have met these conditions, collect the following information:

[listNum]■The full name registered with your wireless carrier.
■The 10-digit subscriber number (mobile number).
■The IMEI number of the phone that can be found by going to Settings > about > more info or by typing *#06# on the phone to get the IMEI number displayed on the screen instantaneously.
■The subscription type of your connection, i.e. prior customer, prepaid, postpaid, etc.
■Registered email address of the account holder (you).
■The last four digits of the Social Security Number (SSN) of the account holder (you).
■Any account passwords.
[/listNum]

After the phone is found eligible and all the information is collected, you can locate the section representing your current wireless carrier below. Follow the instructions to place the unlock request, get the unlock code, and then finally unlock your Nokia Lumia 520 or 1020 from its carrier:
