When I order an Unlock Code for my Samsung Galaxy S4 Active, what will I receive?
With all Samsung Galaxy S4 Active 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.

I had a great experience with unlockbase.com, communication with them is excellent, they respond to you really quick via email and answer to all the questions you have, indeed 24/7. They make sure you understand the process, they are very detailed with what to expect, they were able to unlock my LG V20 from tmobile within their turn arround time which was from 3 to 5 days. I highly recommend them. Great service!!! :D

Great and easy service. Maybe add a little more explanation on which codes to use when you get them. I was given 5 different codes, and I guessed on which one to use. The second choice I made was correct.
