For those of you who want to use your Sprint Galaxy S4 SPH-L720 as a GSM worldphone, you can get your unlock SIM code from Sprint.com.  Now, sometimes even with that, your phone may not work correctly, here’s how to manually unlock SIM on your Sprint Galaxy S4 so you can use use phone when traveling abroad.

*Note – Currently, this unlock method only supports carriers outside U.S., will not work AT&T or T-Mobile.  But I should have an update when there’s a way to do that also.

Before we begin, I suggest you to use a TouchWiz-based ROM or stock ROM for this.

Step 1. Go to Settings->About device and check your Baseband version.  If it ends in MF9, you will have to downgrade to MDC.  If it ends in MDC or MDL, you can skip to Step 6.

Step 2. Turn your Sprint S4 off then hold down Volume Down, Center Home, and Power buttons together until you see warning screen.

howto-unlock-sim-sprint-galaxys4-2

Step 3. Hit Volume Up button to enter ODIN Download mode and connect a micro-USB cable from your S4 to your computer.

howto-unlock-sim-sprint-galaxys4-3

Step 4. Next download MDC modem for Sprint Galaxy S4.  The file name is “SPH-L720_MDC_Modem.tar.md5″.

howto-unlock-sim-sprint-galaxys4-4

Step 5. Next open up ODIN program (download ODIN here if you don’t have it yet) and run ODIN.

You should see a yellow-highlighted box, if you don’t see it, you need to download and install Samsung USB drivers.

Next, choose “PDA” and find the file “SPH-L720_MDC_Modem.tar.md5″ you downloaded earlier.  Then hit the Start button.  This will flash MDC modem to your Sprint S4.

Step 6. Once rebooted, you will see that your Baseband version says “MDC”.  If you don’t see this, try repeating Steps 2 through 5 one more time.

howto-unlock-sim-sprint-galaxys4-7

Step 7.  I found out after doing this, I didn’t need MSL code for this tutorial.  You may need it though so come back to Step 7 if you end up needing the MSL code but you should be fine without it.  so Skip to Step 14.

Next, we are going to get the MSL for your phone.  To do this, go to Settings->About device and hit the Build number about 5-6 times until your phone says, “Developer mode has now been enabled”.  This will allow you to get Developer Options menu.

howto-unlock-sim-sprint-galaxys4-8

Step 8. Make sure “USB Debugging” is checked ON under Developer options then connect a microUSB cable from phone to your computer.

howto-unlock-sim-sprint-galaxys4-9

Step 9. Next, dial ##3282# on your dialer.

howto-unlock-sim-sprint-galaxys4-10

Step 10. Press “Edit”.

howto-unlock-sim-sprint-galaxys4-11

Step 11. When it asks you for MSL code, just enter “123456″ and hit OK.

howto-unlock-sim-sprint-galaxys4-12

Step 12. Next, download and unzip fastboot.zip.

howto-unlock-sim-sprint-galaxys4-13

Step 13. Open a command prompt (by typing “cmd” in Windows search bar), then type:

cd Downloads

cd fastboot

adb shell

su

getprop ril.MSL

This should give you your MSL number for your phone.  Write it down somewhere.

howto-unlock-sim-sprint-galaxys4-14

Step 14.  Next dial “##3424#” on your dialer.

howto-unlock-sim-sprint-galaxys4-15

Step 15. Choose “Qualcomm USB Setting”.

howto-unlock-sim-sprint-galaxys4-16

Step 16. Choose “DM + MODEM + ADB” and hit “OK”.  Then connect a microUSB cable from your phone to your computer.

howto-unlock-sim-sprint-galaxys4-17

Step 17. You can verify everything is working correctly if you see TWO Samsung Mobile USB Serial Ports under Device Manager->COM & LPT.

howto-unlock-sim-sprint-galaxys4-18

Step 18. Download unlock.zip and unzip.  Then run unlock_setup.exe.  This should install the program that unlocks your Sprint S4.

howto-unlock-sim-sprint-galaxys4-19

If you get an error saying you need .NET Framework 4.5, download it here then re-install program.

howto-unlock-sim-sprint-galaxys4-20

Step 19. Once installed, you can run a program called “S4 Flasher”.  Run it then choose “Scan and Unlock”.  It should say “Completed.  Phone rebooting.”  If you see that, your Sprint Galaxy S4 has been fully unlocked.

howto-unlock-sim-sprint-galaxys4-21-s4-flasher

Step 20. Once your phone reboots, dial “##3424#” on your dialer.

howto-unlock-sim-sprint-galaxys4-22

Step 21. Set it back to “MTP+ADB” and hit “Save”.

howto-unlock-sim-sprint-galaxys4-23

Step 22. You can now test your Sprint S4 by inserting another SIM card.  You shouldn’t see invalid SIM card error message, meaning your Sprint S4 is fully unlocked.

howto-unlock-sim-sprint-galaxys4-24

Note that this method doesn’t work currently for AT&T and T-Mobile.  We suspect that Sprint has locked it down for use on other U.S. networks.

As for non-U.S. networks, it should work fine.  Also, you may have to set APN manually by using APN Manager PRO.  (You can take a look at Note 2 World SIM method for more on that.)

I haven’t had the time to test outside U.S. yet (obviously because I am in the U.S.) but if you can test it outside the U.S., don’t forget to leave your comments/hints below.

    I tried this method and it worked for me! I’m in Europe, bought my phone in NYC a few weeks ago, and now Im using a macedonian network. One thing to remember, watch the video instead of following the instructions on this page, since the video has a few explanations that aren’t on this page; like for example that you have to pick your network manually after you are done with everything. Oh, I also couldn’t get through the MSL part so I just skipped that step and it still worked.

    Good luck!

          From the stuff Im reading around the web, it seems we need to root our phones first, and install custom ROMs. I’m really not good at that stuff. Also, I don’t know if rooting will screw up the unlock…

              1. Art

                Did you root your phone before or after you unlocked it? I’m afraid it might ruin the unlock somehow. Also, did you root it by following instructions off of some website? If so, can you please tell me which? Thanks!

                  i rooted it after unlocking… i went that direction because it appears thats the only way to get the data to work.. i only noticed the data wasnt working when i took it to the telco for apn settings… there was already a sim in there at that point and making calls

            OMW! Thank you so much Kevyn! I am in Jamaica and I was so pissed when I came here and realized I couldn’t get data services because APN wasn’t available in phone. Tried a number of things but they didn’t work. What you recommended was the easiest method I have seen. At first I didn’t get what you meant by go to market but then I figure you meant PlayStore. I am officially happy now. Thanks again! :)

    Hi, Step #19 talks about downloading S4 FLASHER, but it does not give a link where it is downloaded from. I tried to find it online in vain. On the instructional video it appears as S4 unlocker, which made me confused. Could you please advise on where I can download it from so I can scan and unlock my phone?

    Also, do I have to have a Sprint sim on the phone during this whole process, or it doesn’t matter if I have it on the phone or not? My phone did not come with a sprint sim.

    I just got my sprint today and after watching the tutorials above I managed to unlock it.
    Am using it on a GSM network in Norway and its working perfectly well though I do not
    have data, am hoping I call the mobile provider to activate my line or send me the internet
    settings. I have not tried the wireless but it managed to ID some networks around, meaning
    its good to go.
    Am also optimistic that it’ll work in Africa. Will get you guys posted when I get there in
    7-8 months time.

      You can root your phone with whichever sim card you want or better still without any. However after you finish rooting try check if you got SuperSu in your apps, this will tell you that your phone is rooted. Put in your desired card. Youshould be able to place calls. Good luck

      @ Rebecca try follow the vid and not the instructions. Remember the basebands and the model # as well as which base model you want to either downgrade to upgrade to. I’d advise you to downgrade and if possible, try axing someone to help if you are having trouble as this is a very simple procedure.

    @Bronda, I followed to video. The 123456 doesn’t work :(
    I have not phone right now and I was hoping I could get this S4 off of Sprint to put it on CSpire/Cellular South. I am so frustrated. As far as finding someone to help, I am the only one of my friends who is “tech savvy”. I don’t know what to do. I don’t have an extra $150 laying around to take it to a store to have it unlocked. :(
    Oh well, no phone, no one to bother me I guess. I don’t know. I need one but I will be fine. I will just resale the ones I have. My CSpire phone CRASHED yesterday and will not do diddly squat.

    I tried this method in order to use Sprint Galaxy S4 in Korea.
    I was sort of lost in the middle of CMD procedure (step 13) but I just ignored and gave up to get MSL number because I couldn’t find where I needed to use this number later.
    Then, I moved on to remaining steps.
    And, it worked. I didn’t even need to install .NET Framework.
    So, I bought USIM from ‘SK telecom’ and it worked. Yeah.
    I did it in Korea. Thanks a lot.

    I followed the instructions above and everything seemed to work fine but when I inserted my SIM it says it’s invalid and the phone seems to still be with Sprint. I’m in Canada so I’m not sure if that has anything to do with it. I also had to root my phone for it to work as well. Any suggestions?

      I got it unlocked now but the SIM doesn’t work. A new SIM will work for a second or 2 but then it doesn’t recognize it after that at all. Has this happened to anyone else?

    I am in Costa Rica and was able to unlock my Samsung Galaxy S4 which I used while living in Las Vegas, Nevada with the carrier Sprint by following these exact instructions. It is now GSM compatible and working with Kolbi ICE network. The only part I could not get was the MLS number in Step 7 but I did not need it. So just let you all know if you download all the programs and files first and put them on your PC and follow each step it should work.

    I REEEEALLY need some help! I somehow screwed up my unlock, so I tried to do it all over again, so I start from step 14 as for the instructions, but when I punch in ##3424# and hit dial I get “mobile network not available”

    Any ideas?

    I am from Guatemala greet me and worked perfectly, only the last step is to connect the network manualnente. settings you configure your mobile network operator will provide the service

    Hi. After 4 daya of searching I found your great youtube video.
    big question. I now know how to enter my msl thanks to you;)
    Now how do you enter nck code. I have the number. Sprint gave me msl and
    nck so I can use it in canada and use the gsm side on my samsung sprint mega
    and no one in canada or the town im in. Toronto knows how to input the codes or
    do a unlock.
    im half way there thanks to you.lol
    please!!!!!! IVE HAD 4 DAYS OF HELL. Can you tell me how to input my nck
    code.
    I figures the s4 is like the mega and maybe ill let a 3rd party unlock store follow
    your video in case I cant find a way to input the nck code.
    Thanka
