How it's Done

I need help in unlocking my Samsung E840. How can I do this?

You will need unlock codes in order to unlock your Samsung E840.

Where do I get unlock codes for my Samsung E840?

For unlock codes, simply contact us at GSMLiberty. We are a registered company with a proven record of providing unlock codes for many models of Samsung phones.

What details of my Samsung E840 do you need to get the correct unlock codes?

Visit the GSMLiberty website and enter the International Mobile Equipment Identity (IMEI) number of your phone and the name of your carrier on the products page. Be sure that you are providing the correct IMEI number as our unlock code server yields results only for valid IMEI numbers.

How do I find the IMEI number of my Samsung E840?

Here are two easy ways to find the IMEI number of your Samsung E840:

  1. Remove the battery and look for the 15 digit IMEI number present on the label located underneath the battery.
  2. Dial *#06#* while the phone is powered on. The 15 digit IMEI number will be displayed on the screen.

Is there only one kind of unlock code?

There are different kind of unlock codes and all of them are not the same. The different kinds of unlock codes are:

  1. NCK stands for Network Unlock Code. Once the code is dialed in your Samsung E840, using the correct steps, you will be able to use your phone with any compatible GSM network.
  2. SPCK is the Service Provider Unlock Code. This code is used if your phone is from the Canadian network Fido.
  3. MCK is referred to as the ‘Unfreeze Code’. You only need to use the unfreeze code if your phone displays PHONE FREEZE when it is powered on with a non-accepted SIM card.

What if my Samsung E840 does not prompt for an unlock code?

If your Samsung E840 does not prompt for the unlock code, turn on the phone with an unaccepted SIM card. Then, enter the following sequence. Also note that the terms Unfreeze/Defreeze, NCK/Network, SCK/Subprovider, SPCK/Provider refer to the unlock codes that were sent to you by GSMLiberty. Substitute the code sequence for the words.

  1. #0199*Unfreeze/Defreeze#
  2. 0111*NCK/Network#
  3. 0121*SCK/Subprovider#
  4. 0133*SPCK/Provider#

    1. Turn on the phone without a SIM
    2. Type *#7465625#
    3. The screen will display Network Lock (ON), Network Subset Lock (OFF), CP Lock (ON), SP Lock (OFF)

where, ON means that the particular lock is locked and OFF means that it is not locked.

How do I enter the unlock codes in my Samsung E840?

There are three ways to enter the unlock codes in your Samsung E840. Also note that the terms ‘KOD’ or ‘CODE’ as mentioned in the steps refer to the unlock code that we provided to you. When you see those terms just type in the code sequence in place of the words.

I unlock my USA AT&T Samsung Galaxy S4 with GSMLiberty code. All I did was put in my new SIM card from T Mobile and input the network unlock code acquired from GSMLiberty. I messed up inputting the unlock code the first time around, but was successful when I input the code correctly. This was a great purchase and extremely easy to execute. I received the code extremely quickly, within 2 hours.
