Regardless of where your location or the network provider you're using, these free issuing unlocking programs are universal. All you need to have to get a Samsung Galaxy S2 unlock code free is just your phone model, IMEI number, your location and the network provider you are using.

Since many Samsung Galaxy S2 unlocking programs are available, choosing the one that suits your needs should be your primary priority. You don't want to be in a position where you were duped by fake "code unlocking" programs which never worked. In this article, we're going to take an in-depth analysis on how we can get a Samsung Galaxy S2 unlock code free and how we can choose between different unlocking programs and methods to make sure that we're on the safe side in this technological world.

Part 1. Unlock Samsung Galaxy S2 with Free Unlock Codes

What is Unlock Code?

For you to successfully unlock your Samsung Galaxy S2, you need to have an unlock code. An unlock code is a unique number usually generated by an unlocking code generator or issued by a network provider. These codes are generated depending on the model of your phone, your location as well as your phone IMEI number.

TIP: You can't unlock your phone without this specific digit code.

Steps to Unlock Samsung Galaxy S2 with Free Unlock Codes

Since we have a lot of different Samsung Galaxy S2 unlocking methods, we're going to take a look at one of the most trusted yet simple unlocking method.

Step 1. Dial *#06# to get your unique 15 digits IMEI number. You can alternatively remove the back casing and the battery of your phone to expose the IMEI number. Make note of this IMEI number since you need it in the next steps.

Step 2. Using our online program, input your Samsung model and your IMEI number in the blank spaces provided as shown below. Click the "Check" icon and wait for some few minutes for the unique unlock code to be generated.

Step 5. Switch on your phone. The moment your phone detects a new SIM card from a different network provider, an unlock code request will be displayed. At this point, our unique unlocking code from step 3 comes in handy. Input this code in the spaces provided and press "OK".

TIP: Please note that the moment you input the unlocking code three consecutive times, with each trial being unsuccessful, your phone is going to be blocked completely. Inserting your original SIM card won't help either. If this happens, you have no other option but to contact your original network provider to have it unblocked.


As we have seen, unlocking your S2 using this method is a simplified process. However, caution should be taken when using code-generating programs. Just like any other program, our unlocking method comes with both advantages and disadvantages. The following are some of them.


  • It's free and easy to use.
  • It only takes a few minutes to unlock the phone.


  • It requires a new SIM card.
  • It can accidentally delete your personal data.
  • It requires an unlock code for Samsung Galaxy S2 to operate.
