    I have a Samsung galaxy S4, It was completely paid for but the account they claim is not in good standing. Despite they unlocked my daughters phone after we switched carriers they wont unlock my S4.

    it is a Samsung SPHL720T (MODEL)
    IMEI 990004415656788

    USA SPRINT

    COUNTRY AND CARRIER

    PLEASE HELP , They are a bunch of jerks, I own they phone and they dont care. once I transferred my service to another carrier they wont help me to use the phone I paid for.

    This is what I found:
    How to SIM Unlock the Galaxy S4
    This method is totally free, but you have to be careful and follow every step without mistakes, because otherwise you might brick your device. So make sure you don’t do anything wrong and that your phone has enough battery so it won’t turn off during the process.

    This should work for all variants of the Samsung Galaxy S4, including I9500, I9505, I9506, I9505G, I337, M919, I545, L720, R970, I959, I9502, I337M, M919V, R970X, and R970C.

    1. Open the phone dialer
    2. Dial *#0011#
    3. Press Menu
    4. Tap Back
    5. Press Menu and open the Key input
    6. Enter 1 and press OK
    7. Press Menu and tap Back
    8. Tap [1]UMTS
    9. Tap [1]DEBUG SCREEN
    10. Tap [6]PHONE CONTROL
    11. Tap [6]NETWORK LOCK
    12. Tap [3]PERSO SHA256 OFF
    13. Press Menu and then Back
    14. Tap [6]COMMON
    15. Tap [6]NV REBUILD
    16. Tap [4]RESTORE BACK UP
    17. Now your device will freeze, but don’t worry. Be patient and press Menu when you can, then Back key ON.
    18. Your device will now reboot.
    Now your Samsung Galaxy S4 should be SIM unlocked.
