Samsung S4 Unlock code won't work i9500XXUBMG9

I have purchased the unlock code for Samsung Galaxy s4 with i9500 and originally purchased this from Saudi Zain telecom and it didn't work...here
and it ask for unlock code...and I did purchase this from unlocker unit and still it won't work and please someone help
I don't have service mode option working and it is stock and formatted the phone and using the new sim card and tried everything and it doesn't work...please advice
There is no unlock code for the L720! You got scammed. If you want to unlock the phone for use on other carriers look for the threads on here that explain how to do it.

Rooted s5- unlocking ?

Hi,
I just got Galaxy S5 900F locked to vodafone uk. I found a tutorial called UNLOCK, flash and root your s5 4.4.2. It was actually comming from this website. I rooted it but it is still locked. I think rooting didn't really unlock my phone(as tutorial said) as it wants me to type the sim code in. Is there any way to unlock it free? If it isn't whats the cheappest way? Thanks

Question about S5 (T-mobile) and unlocking sim/bootloader/running cm12

First off, sorry for the confusing thread title.
I'm currently running an AT&T Note 3 which has a locked bootloader and I've wanted to run CyanogenMod for a while now. I've ordered a second hand T-Mobile Galaxy S5 because I've heard the bootloader is unlocked and/or unlockable.
Can anyone here clarify how the sim lock/carrier lock works?
Will this require me to purchase an unlock code or will flashing the bootloader and custom firmware automatically unlock the sim? From my research I've read that I still need to unlock the sim, but I've also read that using a different bootloader can unlock it. Kind of confusing.

[Q] SIM unlock i9506, any news?

Hello,
I've been digging the forums and the net if there is any way to sim unlock the i9506 for free.
All the tutorials, etc refers to the i9505 but not the i9506. I was not able to find any free solution to the date.
Does any one knows if there is any free method today in 2016? Maybe all the info I've found is outdated and old and perhaps there is a new way/method to sim unlock the S4 i9506.
I've downgraded to 4.4.2 and tried the *#0011# method without luck.
Any help would be appreciated. Thanks in advance.
The only free SIM unlock method for your device is asking your carrier for a code. SIM unlock worked on the I9505 by downgrading the firmware to Android 4.2.2 and then using one of the methods mentioned in the thread. The I9506 never had Android 4.2.2, thus no way to SIM unlock.
