When I order an Unlock Code for my Samsung D428, what will I receive?
With all Samsung D428 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.

This is a wonderful solution if you're trying to unlock your phone. I had a ZTE Z812 AT&T phone. I needed to use it in Singapore. I requested the unlock code from UnlockBase, and within 15 minutes I had the code. It worked!

Validation process nice, so they protect your information and themselves as well. I woke up on moday morning and got the email with the unlock code already. Your unlock code is the NCK code. Other than that, WONDERFUL SERVICE! Secure and fast!

Instructions weren't exactly as I experienced but I eventually got it to work. If the phone has a clean number and if you agree with the instructions then the service is easy to access and reasonably cheap.
