When I order an Unlock Code for my Samsung Galaxy S3, what will I receive?
With all Samsung Galaxy S3 Unlocking Code orders we usually deliver a complete set of unlocking codes. Most of the time you just need the Network Code (NCK) but when needed you'll also receive Unfreeze Code, Reset Key, or Service Provide Code. In the same email that includes your unlock code(s), you will also receive complete instructions on how to use it. Usually, you just insert the SIM card in the phone you want to use and the phone will prompt you for the unlock code.

This is really a 24/7 service... I unlocked my Samsung SM-G930W8 in 15 minutes after i did the payment... I recommend.
All I used was a USB wire to connect to my Laptop and follow the instructions that was sent to me in the email.

Chose Unlockbase because of it's web layout and made the right choice. Code came quickly and was really easy to do even for a novice like me! Good value for the money.

Happy user of an unlocked Blackberry Q10. I have tried other services however others weren't able to unlock it. Great job to the provided service. The prices were attractive as well
