How to enter unlock codes on all Samsung models

Different phones have different Unlock Code Input Instructions, Try the following Instructions in order:

Method #1 Insert a Non accepted simcard in your phone and power on. Once finished loading your phone will ask you to enter a code, enter the Unlock Code

OR

Method #2 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)

Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)

OR

Method #3 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)

"Phone Freeze" message. - What do I do?
 
Phone freeze is a result of the incorrect code being inputted incorrectly too many times, which means your Samsung device is Hardlocked.  You will require a Defreeze code and a Network Code to Unlock your phone.

* If you received multiple codes from us in the format below, use the Phone freeze instructions above.

Example:

NETWORK=xxxxxxxx; PROVIDER=xxxxxxxx; SUBPROVIDER=xxxxxxxx; DEFREEZE=xxxxxxxx


* If you received a Single code from us, you only have the network code.  If you are receiving the "phone freeze" message, you will require a Defreeze code from one of the manufacturer methods.  You can contact us directly regarding this.
 

How to enter defreeze code for "Phone Freeze" Samsung devices (only if your Samsung is hardlocked)

  1. Input a non-accepted simcard into the phone.
  2. Proceed to the dial screen.
  3. Enter the defreeze code (Freeze code) and press enter, or okay.
  4. The screen should now ask for the unlock code (Network Code).  Enter the 8 digit unlock code and hit enter.

OR

 I can make calls and text but I'm not getting internet/data service.

In this case you will need to adjust what's called the APN settings.  The APN settings vary depending on the service provider you are trying to use.  Please contact your service provider and they can assist you setting this up.  There is no separate unlock for data or internet.  If you can call or text, your phone's network is fully unlocked.
