Sim unlock code

I recently received an unlock code for my GS4. Could this code be used to unlock another phone? Or is this code only valid with this GS4's IMEI number? Thanks!

It is tied to your IMEI number, so only your phone.
in the old days it might have; now its tied to your IMIE
Here is a guide on how to unlock your s4.

Network Unlock u8800-51

Hi,
Is there anyway to remove the network unlock of my ATT Impulse (U8800-51)? I try to flash it with different roms and it always ends up asking me for a network unlock code. I bought one on Ebay but it does not work. Thanks

How does an upgrade of firmware just SIM unlock a phone?
Can anyone else confirm this?

It changes the carrier configurations and somehow unlocks it. Try it

Huawei releases general versions, not specific ones for carriers like Samsung does. So when you flash it it doesn't include your carrier lock information. Just flashing B512(is an international version) over another BXX will unlock the phone.

Sim unlock (operator) NOT regional lock - possible with tools from XDA?

There was sim unlock for my old trusted i9100. Are there same tools/method for N9005?
Yeah. Just download the RegionAway made by Chainfire from the playstore. Its a paid app but very cheap. It will sim unlock and region unlock your N9005. At least it did for me. You will need to root your phone though to make the application run and do its thing. My N9005 was SIM locked to 3 UK network. After rooting, downloading and running chainfire's app, i am now using my Tmobile UK sim in it. Best of luck and hope this helps. Let me know if i can be of assistance.

Thanks! Very interesting indeed! But I wonder what Chainfire will say about sim unlock. Coz he says "but it may or may not remove the SIM lock". If it removes SIM Lock and Regoin Lock it is miracle app!
And very cheap really! But it is easier for me to donate via paypal.

Hi is this the only way to sim unlock my uk note 3 n9005 so i can change.sim also after i have rooted and used region away to unlock sim can i unroot and will it still be sim unlocked or not thanks
If you are a 3 user I believe they will sim unlock it for free. Most UK providers will offer this service but some may charge .

Unlocking with carrier provided code

My contract just expired so got an unlock code from AT&T, but it doesn't work. According to the instruction email, it won't work on a rooted device.
Does anyone have experience, if I odin to stock, would the unlock code work, and if the phone would stay unlocked if I flash a custom ROM?
Also, could anyone post the files to odin to MDL? The link it the thread that had it no longer works.
Thanks.

You cant unlock with at&t sim!!
You need tmobile sim card to unlock. If you tried already go head back to stock do unlock aim with different carried sim then flash what ever rom you want.
Good luck

Thanks. Luckily I have a Peruvian SIM card, from when I traveled, I used that to trigger the code and failed twice to unlock. I know I only have 5 attempts total so I wanted to make sure to get it right the next time. Did you tried just unrooting on your custom ROM? I'm wondering if that would be enough or going back to stop is required.

Which firmware version were you on when he tried? I believe you have to be on an older firmware first like PC5 before it'll work.
Flash your phone to PC5 and try again.
