How to enter my Unlock Code on Samsung ?


General instructions (will work for most Samsung phones)

Important: Our Samsung unlocking process is 99.9% accurate if you provide the correct information. Therefore, a video proof will be required if code error occur for verification. It is also good idea to film your unlocking process.

General instructions (will work for most phones):

Turn off WIFI and turn off your Samsung phone
Insert a non-accepted sim card (different from the original carrier). 
Turn on the phone. 
Slide to unlock and it will ask for the unlock code
Enter the unlock code you obtained from iTechUnlimited.com
Your phone is now fully unlocked!


If you get "Network Unlock Unsuccessful" message, don’t worry. This is a very common problem and there are different ways to solve it. We explain this below.


If the phone shows the message “Phone Freeze" with an unauthorized sim, this means someone already has tried wrong codes many times and has hardlocked the phone. You will need a defreeze (also called unfreeze or stuck code). If the defreeze code was not sent to you, please contact us.

If you enter an Unauthorized Sim Card and phone does not prompt to enter Unlock Code and your Samsung is android, Go to the dial screen and press #7465625*638*# Once prompted for code, enter 8 digit Unlock Code provided by iTechUnlimited.com.

Or

If you see "No Valid Sim Card" after you insert an Unauthorized Sim Card, remove the Unauthorized Sim Card and use the Authorized Sim Card or with NO Sim Card and follow this instruction.

1.Type #7465625*638*CODE# (CODE is the Unlock Code we sent you.)
2.Phone deactivated message means its unlocked

Or

1.Switch ON the phone without a Sim Card (if this does not work try with a Unauthorized Sim Card first and if necessary try an Authorized SimCard )
2.Type: #0111*CODE#  (CODE is the Unlock Code we sent you)
