How to unlock a Samsung Galaxy S IISamsung Galaxy S II unlocking instructions We reveal how to get an unlock code for your Samsung Galaxy S II and how to choose a reliable supplier. First, a bit of background on the phone itself. The Samsung Galaxy S II, otherwise known as the GT-I9100, is the second edition of Samsung’s popular Android smartphone series.  The Galaxy S II was released in 2011, and quickly developed a reputation for being lightning fast, and having an unusually light and slim case that established the style to beat for Android phones. At the time of its release, it was widely acknowledged as the best Android smartphone on the market. With more than 20 million units shipped, the Galaxy S II was the primary contributor to Samsung beating out Apple for smartphone market share in the third quarter of 2011.

Your carrier has locked your S II to stop you using it on other networks.

There are still some limits to the phone as it is shipped, however. Although the Galaxy S II is a GSM phone, it is shipped with a SIM lock preventing you from being able to use your phone with carriers other than the one from which you purchased it. To unlock Samsung mobile phones, you’ll need Samsung-specific unlock codes to remove the SIM lock with which the phones are shipped.

Be careful of Free Unlocking Service, more often you will end up with a phone that doesn’t work.

The good news is that it’s possible for you to unlock a Samsung phone for free. Some phone carriers will give you a new SIM card and the required code you need to unlock Samsung mobile phones if you call them and give them your phone details. Being able to unlock a Samsung phone for free is better than having to buy a SIM card and pay for Samsung unlocking codes, so it’s definitely worth giving your provider a call before following other avenues. If they give you the unlock code, follow their instructions to unlock the phone.

Getting an Unlocking Code for your Galaxy S II from your Network Operator can cost a lot of money

If your provider doesn’t want to give you the Samsung unlocking codes, don’t despair! You just have to buy a SIM card and one of the specific Galaxy S II unlock codes from a vendor. The SIM card needs to be associated with a phone carrier other than the one which is your phone carrier.

Once you receive the new SIM card and unlock code, you don’t need anything else to be able to unlock your Galaxy S II. Simply follow these steps.

1. Power off your phone.

2. Remove your existing SIM card, and replace it with the new SIM card for a carrier other than the one which is your current carrier.

3. Power on your phone.

4. The phone will either prompt you for your password, or warn you that you have an incorrect SIM card and prompt you to insert the correct one.

5. If you receive the password prompt, simply enter the unlock code you were given. Otherwise, enter the following code string, where nnnnnnnn is the 8-digit unlock code you were given: #7465625*638*nnnnnnnn#

Once you have successfully unlocked your phone, you will be able to use your Galaxy S II with any GSM carrier.
