How to Carrier Unlock Your Samsung Galaxy S4

Warning
Before you start, make sure your device is backed up. Messing around with SIM carrier stuff can be risky, so you never know. It might explode. Not our fault.
Step 1: Dial the Secret Number
Launch the phone dialer and enter * #27663368378#, but DO NOT press call. The phone will automatically take you to the ServiceMode menu.
Step 3: Select Debug Screen
You should now be at UMTS MAIN MENU in ServiceMode. Select [1] DEBUG SCREEN.
Step 4: Select Phone Control
At the DEBUG SCREEN, you'll see six options. Select [6] PHONE CONTROL.
Step 6: Select Perso Off
On the next page, you should see three options. Select [3] PERSO SHA256 OFF.
Step 7: Go Back to Main Menu
Now, head back to the Main Menu by tapping on the Menu button and then the Back key (from the menu).
Step 1
Go to your home screen ( using a custom launcher) and Long-Press on an empty spot. The “Add to Home screen” menu should appear; Tap Shortcuts.
Step 2
From the next menu, Select Activities .* Now you should be at a black screen with a list of phone activities. Slide-down to whatever activity you can find with “ hiddenmenu ” in the name. (e.g. on my Samsung Galaxy S Epic 4G it was called com.android.hiddenmenu.)
Done!
Now you have a shortcut to one of your hidden menus on your home screen, and you can keep adding them to your heart’s content. I first chose the RTN hidden menu because several people were wondering how to access it on phones that don’t support the # codes after reading our previous article.
