How to unlock ur samsung galaxy s4....for any simcard Unlocking your Samsung Galaxy S4 so you can use a different SIM card isnt the easiest thing in the world. In the states, unlocking cell phones was actually made illegal this year, despite the White Houses disapproval, though, a new bill is making its way to the House floor as we speak that will make unlocking legal again—if it passes. If youve purchased a GS4 with AT&T, T-Mobile, or another GSM provider on a contract, then your phone is probably locked. While they may be reluctant, most carriers will unlock your device for you, but only if youre leaving the country or if your contract is up. How fair is that? If youre really desperate to pop another SIM card in there and dont want to wait, you could shell out a few bucks at your local sketchy-looking prepaid store or online, but why pay when you can do it for free? How to Carrier Unlock Your Samsung Galaxy S4 With this softModder tutorial, were going to show you how to quickly and easily unlock your Samsung Galaxy S4, models GT-I9505 and GT-I9500. If you have a different model, check out the note at the bottom of this article. 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 2: If That Code Fails... In case *#27663368378# doesnt do anything on your model, try entering *#0011# instead. This will take you to the basic information section of ServiceMode. From there, press the Menu button on your device and then the Back key in the menu—not your phones menu key. Tap on the Menu button again, but this time press Key Input. Enter 1 and press OK. Wow. A lot harder, right? 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, youll see six options. Select [6] PHONE CONTROL. Step 5: Select Network Lock From the Phone Control screen, select [6] NETWORK LOCK. 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 8: Select Common On the UMTS MAIN MENU, select [6] COMMON. Step 9: Select NV Rebuild Now, tap on [6] NV REBUILD. Step 10: Restore Back Up & Reboot Finally, the phone will notify you that a Golden-Backup exists. Select [4] Restore Back-up. Your Galaxy S4 will now reboot automatically, which might take a few minutes. Once its back on, the network will be unlocked, allowing you to use any SIM card that will work in your model phone.
