i want to unlock my cellphone from the carrier Telcel. so i have doubts about this website http://www.cellunlocker.net/ and reading others post iam afraid that i cant unlock my cellphone. i was talking with the salesperson that sold us the cellphone and she said the only way to unlock the phone is when the contract ends ( in 2 years) http://imageshack.us/photo/my-images/692/201305152339041.jpg/

2. Open dialer, type *#0011#. Press the Menu button and then back (on menu, not button). Press Menu button again and select KEY INPUT. Enter 1 and press the OK button. One more time, press menu button followed by back BUTTON.
2 Follow this instructions http://www.droidviews.com/how-to-sim-unlock-t-mobile-att-galaxy-s4-sgh-m919-sgh-i337/

You can try with that firmware. If it doesn´t work you definately must use the I337MVLUAMDJ firmware.

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..

Mine restored just to test and still get Invalid SIM for domestic TMo SIM card

From settings - more networks - mobile networks - network mode choose gsm/umts and you will see the status screen like in the tutorial..
But if you do menu - back - menu - input and type 1 you will get to the umts screen

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?

Did sprint fixed the issues (similar to the HTC one) of unlocking the SIM for use with local (abroad/international) SIM?Wanted to be sure before purchasing.

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.

Phone unlock won't work

I followed this guide to unlock the phone
http://www.android.gs/sim-unlock-samsung-galaxy-s4-i9505-i9500/
1. You need to launch the Service Mode on your phone; in order to do that tap “*#0011#” in the dialer of your handset.
2. The Service Mode will be displayed; now you need to tap on “menu” (left soft key) and from the dropdown menu select “back”.
3. Press the Menu button once more and this time select “Key input”.
4.. Tap on the pop-up box that will be displayed; then enter “1” and tap on “ok”.
5. You now need to go back to the Service Mode menu; for that tap on “menu” and select “back”.
6. From the Service Mode menu, this time select “[1] UMTS”.
Click to expand...
Click to collapse
At stage 6.... there is no menu that says UMTS
It just simply takes me back to the original menu with stuff like "GSM900: Limited" etc
It takes me back to the very first menu after I dialled “*#0011#”
So.... what do I do...??
The reason I'm trying to unlock the phone is that it said, "Network not registered".... It won't let me connect to an EE network at all... so I thought maybe the solution is to unlock the phone.
Thanks

Is the sim activated? Could the imei be blocked by the carrier? If you are not bring prompted to enter a network unlock code, the phone could already be unlocked.

You should be asked to enter unlock code before yu try to unlock it.

In order for the service menu method to work, you MUST downgrade your modem to an Android 4.2.2 version first. Only then will you be able to access the appropriate menus. We have an entire thread on the topic of SIM unlocking in the General section of the forum, and mention of the modem downgrade really doesn't start showing up until posts from November, 2014. That thread has also pretty much switched to using RegionLock Away to blow away the SIM lock, as it's a more robust solution than the service menu method.
Now, will it help you regarding the EE SIM? Probably not. But it will allow you to use a SIM from any carrier.
