How to Unlock the Code to a Samsung Cell Phoneby Palmer Owyoung ; Updated September 28, 2017
Samsung phones are known for their good looks and cutting-edge technology. Chances are that if you purchased one through your mobile service provider, you probably got it at pretty good price, but you also likely received a phone that was locked. What this means is that you won't be able to use it on a different network, which can be a problem if you travel overseas. The simple solution: get the unlock code.
Type "*#06#" into your phone and a 15-digit code will appear. Write it down. This is known as the international mobile equipment identification number or IMEI for short. It is the serial code for your phone.
Call your mobile phone service provider and ask them for the unlock codes for your particular model of phone. They may refuse at first, but be persistent and tell them that you are going on a trip abroad and would like to use your phone with a different network overseas so that you won't need to pay roaming charges. If they still refuse then you will need to purchase your own codes.
Go to a cell phone unlock site such as GlobalUnlock.com, TheTravelInsider.info or GSMLiberty.net. These sites will provide you with unlocking codes for a fee. As of 2010, it generally costs between $12.99 and $25.99 per code.
Go to the site and enter your IMEI code into the appropriate box. Choose Samsung for “Make,” then select your model from the drop-down box. Put in the country where you live along with your mobile service provider and click “Enter.”
Enter your credit card or PayPal details and email address and click “Make Purchase.”
Check your email in 24 to 48 hours and your unlock codes should be delivered. Open up the email and write down the codes.
Turn your phone off and take out the battery. Remove the SIM (subscriber identification module) and replace it with one from a different network. Put the battery back into your phone and turn it on. When it comes back on, it will tell you that the phone is locked and will ask you for the code.
Enter your unlock code exactly as it is written. Do not add any spaces or additional characters. Click “OK” and the phone will beep, blink and restart. When it comes back on, it will tell you that the phone is unlocked and you will see the name of the new network at the top.
