Samsung Galaxy S4 is indeed the best smartphone for the moment. Even there are many smartphone featured with great specs, but there is hardly can be found which can stand side by side with this device. Surely there are many person who hold this monster right now, it can be known by the number of the sale of the Samsung Galaxy S4.
As a rule, you can get almost any device unlocked by paying a small fee directly to the carrier, or to several online services that would let you purchase an IMEI unlock. However, in my personal experience, nothing beats the feeling of doing such a process yourself, and save those precious bucks in the process.
On this article i will show you how to SIM unlocking Samsung Galaxy S4. But keep on mind that this tutorial is for those who expert of doing the stuff because this could damage your device.
Before we proceed, please be advised that the usual disclaimer applies. Playing around the carrier lock is risky business, and more complicated than your average Android modding. Follow these instructions at your own perusal. Redmond Pie cannot be held liable for any loss whatsoever resulting from following this method. Also, this method applies to GT-I9505 only, and not to other variants of Galaxy S4.
Step 1: Launch the Phone app on your Galaxy S4, and dial in: *#0011#
Step 2: Press the Menu button followed by the Back key. Then, hit the Menu button again and select KEY INPUT. Enter 1 and press the OK button to enter ServiceMode.
Step 3: Press Menu one more time and tap back again. This will pull up the Main Menu for ServiceMode. Tap [1] UMTS.
Step 4: Now select [1]DEBUG SCREEN, followed by [6] PHONE CONTROL.
Step 5: From the next screen, pick [6] NETWORK LOCK.
Step 6: You’ll get three options. Hit the one that says [3] PERSO SHA256 OFF.
Step 7: Now, you need to get back to Main Menu. To do this, hit the Menu button followed by the Back key. In Main Menu, now pick [6]COMMON, and then [6] NV REBUILD.
Step 8: The phone will tell you that a Golden Backup exists. Tap [4] Restore Back-up.
Your device will now go through a series of “conditions”, where it will first freeze, then get on a black screen with Blue LED on and both capacitive buttons on, after which it will reboot automatically. The whole cycle might take a couple of minutes, so be patient. Once it powers back on, it’s network unlocked, permanently. Enjoy!
