Do unlock codes permanently remove the lock from the phone?

Genuine unlock codes will permanently remove the SIM lock from your Samsung C520 phone without affecting any of your phone’s software.

What details will GSMLiberty need in order to search for the unlock codes for my Samsung C520 phone?

We will need the first 15 digits of your phone’s IMEI number without any dashes or spaces and the name of your carrier. You can enter these on the products page of our website.

What does IMEI number stand for? Why is it important?

IMEI stands for International Mobile Equipment Identity. Your phone’s IMEI number is unique to your Samsung C520 phone and positively identifies it. We use this number when we search for your specific unlock code.

How can I find the IMEI number in the phone?

Here are two methods to find the IMEI number on your Samsung C520 phone:

  1. Remove the battery and look for the 15 digit IMEI number present on the label that is located underneath the battery.
  2. Dial *#06#* while your Samsung C520 is powered on. The 15 digit IMEI number will be displayed on the screen.

I found two different IMEI numbers. Which one should I use?

It is important to use the IMEI number you found on your phone by using one of the two methods explained above. If there is a different number on the box, it is not the correct number, please do not use it.

I unlock my USA AT&T Samsung Galaxy S4 with GSMLiberty code. All I did was put in my new SIM card from T Mobile and input the network unlock code acquired from GSMLiberty. I messed up inputting the unlock code the first time around, but was successful when I input the code correctly. This was a great purchase and extremely easy to execute. I received the code extremely quickly, within 2 hours.
