Yea im not using it for CDMA also i just need it for GSM/UMTS since my country need only this..
any idea?

You can't put any other SIM than Sprint.
Only way you can use this phone now anywhere in the world is on CDMA network using PRL and NV. for now GSM is locked and Sprint also had no clue how to unlock.

I believe the CDMA workshop is the tool used to unlock the SIM card.
search for "Sprint Samsung galaxy s4 16 digit password"
it won't take you directly to what you want but it is related and should lead you there.

After you type the code press menu and then choose Back from the menu itself not the hardware back button.. Then menu again and choose input from the menu..

Galaxy s4 sprint unlock international gsm

Hello i'm in mexico and i have a galaxy s4 whit bad esn
i try to put a sim card (telcel) but only shows " not valid sim card''
i pres #*06# to obtain the imei and it show me the imei.
My question is. It's a hidden menu keys to press to access the unlock code?
I will apreciate if one of you have unlocked their sprint phone and tell me how. Thanks

If you have a bad ESN, I'm afraid Sprint will not give you the unlock code to use an international SIM. The code will have to come from Sprint....I think you're out of luck.

Response Via Email (Chris T.) 05/23/2013 04:47 PM
Thank you for contacting Sprint regarding unlocking your device. At this time, since you live outside of the United States and not a Sprint customer, we would be unable to assist with unlocking your Sprint phone. Sprint Policy requires:
1) the device be on an active Sprint Account
2) the account be at least 90 days old
3) the account not be delinquent
4) the account not be on an Account Spending Limit
Without meeting these requirements we could not unlock the device. The request is sent out Over the Air on the Sprint Network and that is why the device has to be on our network for us to assist.
Thank you,
Chris T.
Senior Specialist
Sprint Worldwide
Tues-Fri 2pm-11pm CST
Sat 12pm-9pm CST

Once the device is unlocked you wouldn't need to do anything with sprint any longer right?

I was have galaxy s4 from sprint and try the method s mentione but doesn't work the only solution for me was activated the phone on boost mobile network the galaxy s4 sprint has cdma and gsm GSM basebands can be use only if sprint unlock for international use

Can we try by Flashing Tmobile S4 M919 or AT&T S4 Firmware to Sprint Galaxy S4?
Has anyone try to Flash other GSM (Tmobile / AT&T) Galaxy S4 Stock Firmware into the Sprint Galaxy S4?
Maybe we can then try the FREE SIM Unlock Method.
Anyone care to comment if this is possible?
Thanks!

I'm living on Mexico too and tried method below, after the phone restarted I put a new sim card but no luck on activating, it just say "no sim card"
My phone is not a bad esn, any other ideas on how to check if it is really unlocked?

Did somebody try "CDMA tool" ? They say it is compatible with the Sprint Samsung Galaxy S4. I can not do because I do not have the phone.

I work for sprint and they would not unlock my S4. That just shows how hard it is to get them to unlock

[Q] Cannot get to Service Mode menu

Hello
I'm hoping someone can help me with this problem. I need unlock phone as I am moving in a few weeks and will need to use a new sim card. I have an unlock code but it is not working and I believe the reason is a while back a tried the free unlock method that has been online for a while and I was able to follow the steps fully (it didn't work to unlock my phone).
Now trying to follow the same steps again, I cannot where I enter *#0011#, choose back from the menu, then key input and enter 1. This used to bring me to the main menu but now it stays on the same page and does not change and I cannot access the main menu.
If somebody knows how to access the main menu a different way or fix this problem I would be very grateful :fingers-crossed:

How to fix samsung s4 thats not accepting network unlock code after free unlock
So I finally got it working. So i'll post this in case it helps some else having this problem.
You need to flash an earlier version of the firmware to allow you to access the main menu in service mode
I went to this forum http://forum.xda-developers.com/showthread.php?p=39176955
and downloaded the odin v3.04 program and then the XXUAME2 modem from the list.
Then after installing odin I chose phone, chose the extracted .md5 file from my computer and connected my phone to the computer using the usb.
Turn the phone off then switch it on whilst simultaneously holding the volume down and home button and then use volume up to confirm.
Click start on odin and wait for a few mins until the box at the top changes to pass.
Follow the rest of the steps stated in the forum above
After the flash, follow the instructions in this video https://www.youtube.com/watch?feature=player_embedded&v=cY4LcdO2WAE
Restart the phone with a locked sim and try the unlock code now, it should work.

Give this a try. You might have to figure out a new phone app dial number for step one as this is just copied and pasted (quite a while ago) from somebody on here i wish i could credit.
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.
