Samsung Galaxy S4 has been named one of the most powerful Android smartphones around. In the United States and United Kingdom, users can buy the device with contracts from networks. In Asia, there are prepaid versions but there are also paid plans. For users who have no choice but to pay for a contract, it can be a breath of fresh air to know how to unlock the Samsung Galaxy S4 for free.
A handy code can do a difference for those who want to own a Samsung Galaxy S4 device. Some users feel that being locked with a specific network is a disadvantage. For instance, having a phone under contract will be problematic once the person goes to another country. Likewise, those who started with another network but like to transfer to another, feel it at as a dead end. Imagine wanting to use the same device but needing to purchase a similar one because of network issues. It can be a waste of money.
Those who wish to unlock their phones to use it as freely as possible, follow these steps according to Sidh Tech:
1. Remove the SIM card and replace it with preferred carrier or SIM.
2. Turn off the device then turn it on again.
3. Go to the phone's dial pad and type the following: *#197328640#.
4. Go back to the menu and access UMTS.
5. Click on Debug Screen > Phone Control and Network Lock.
6. Proceed with Options > Perso SHA256 OFF.
7. Wait for a couple of minutes before going back to the main menu.
8. Wait for the message 'Network Lock' then choose NW Lock NV Data INITIALLIZ.
Given the user provided the right sequence, it should read: Asterisk Pound One Nine Seven Three Two Eight Six Four Zero Pound. It is important for users to understand that some refer to the asterisk as the "star" while others refer to the pound as the "hash."
This should unlock the phone and give the user freedom to use it. The code has been available for quite some time now. Other Samsung users may find it useful.
