When I order an Unlock Code for my Samsung Galaxy S4, what will I receive?
With all Samsung Galaxy S4 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. In case you need any assistance, our customer support is always there to answer any questions you might have. We will get back to you within less than 12 Hours from Monday to Friday.

They came thru and were able to unlock a MetroPCS/TMobile phone that was ineligible due to not being on the MetroPCS network for 6 months.

It worked without trouble the first time. The code came in about 24hrs, I keyed it in and presto! : the phone unlocked.

Unlocking service was very fast, it lasted altogether less than 15 minutes. It could have been a bit cheaper, but very satisfied with instant license delivery and overall service.

Literally, 2 minutes after making the purchase, I got the code emailed to me and 4 minutes after turning on my locked phone and adding the sim card, my new phone was unlocked. And it only took 4-6 minutes. I will recommend UNLOCKBASE to anyone. Thank you guys!
