I want to know what the best method is for unlocking my Galaxy S4 SGH-1337 MF3 build Currently running on the airvoice network. I do NOT have an AT&T account but should I still give them a call and ask for an unlock code? or use an unlocking service? also from my understanding there is no sim unlock method for the MF3 build currently.
Thanks in advance!

If you pay full price, give them a call and they might give you the code.

First, unlocking the sim card is not related to the version of your phone.
So if you bought it from At&t with full price, some of them they will tell you to wait 90 days before asking for the unlocking code.
If you bought it from someone, ask the previous owner to call them and to ask for the unlocking code. Otherwise, use google, and try your luck.

are you talking about unlocking the phone to works with other carriers? yes you can on any version.
or unlocking the bootloader so you can use other custom roms? is yes, then you can't. only roots.

I'm talking for other carriers. and I tried the *#0011# method and the other one witht the long string of numbers I cant remember but it never goes to the menu to let me choose [1]UMTS.
free unlock method has been known to screw people's phones up. There are several warnings throughout that thread the mention it.
Just go with the options that I mentioned, or use google, such as "Auction website" they do some kind of these service I guess.
Actually, on the AT&T MDL and MDB firmwares you were able to sim unlock it through service menu:

MF3 blocked this, so the only way you can get your phone sim unlocked with the update is using ebay or cellunlocker but at a price.

Yeah that's what I thought the case was. Oh well, back to trying to trade my At&t S4 for the Verizon version. Swappa is such a drag.
So I have seen multiple people here on the forum claiming to do it or wanting to do it and I am a bit confused. I have an s7 edge on contract from ATT. Can I do this? If I flash T Mobile's firmware on this does this make my phone usable with a T Mobile sim?
Thank you

Can you advise the procedure? I'm currently permanently locked to AT&T network and would like to use a carrier (SK Telecom - Korea).
Wouldn't you still need to SIM unlock your AT&T phone to use on T-mobile network? I don't think just flashing another carriers ROM will allow you to use their network. Am I Wrong in thinking this way?

I am confused. Can I not flash the phone with t mob firmware without unlocking? I thought this was just a software restriction and would have been removed by flashing a new firmware.

Flashing the phones firmware will not carrier unlock the device. That is tied to the IMEI. It will boot up the Tmobile software, but it still will only work on AT&T network.
Also in order to unlock the device from AT&T they will most likely bill you for the remaining value of the device as soon as you request an unlock code. You cannot take a phone from one carrier to another unless it is fully paid off.
I have an Unlocked AT&T S7 and I can put in a T-Mobile sim and it works. So why Flash T-Mobile onto an AT&T phone if its Unlocked??? My AT&T S7 is Paid for in Full.
My question is, if you do flash T-Mobile firmware on AT&T phone will you get OTA updates off of T-Mobile, like when Nougat comes out????? Also would you still have wifi calling and get all the LTE bands of a T-Mobile phone????

Yes. All the edge models have identical hardware. Their only differentiating factor is the firmware they run. I flashed the unlocked firmware onto my AT&T model and now get updates directly from Samsung. If you flash the T-mobile firmware on the AT&T device, all features will work and updates will come from T-Mobile. Same would work if you flash the AT&T firmware onto a T-Mobile variant. Or Verizon to Sprint, Sprint to AT&T, etc.

So you are saying this about S7 Edge, does this work the same for the AT&T S7 SM-G930A? Mine is not the Factory Unlocked model but I got the unlock code from AT&T. I thought the firmware came from the carrier and not Samsung on updates on a carrier branded phone???
So if I flash T-Mobile into my AT&T S7, I can also flash it back to AT&T firmware should I go back to AT&T???
Think you are talking about flashing firmware on your that is original for the Factory Unlocked version, think its SM-G930F

Well people on the S7 edge have flashed the tmo firmware on their AT&T models. Updates come from carrier on branded phones. So if you have an AT&T phone and flash another carriers firmware, it would only be branded by the physical logo on the back. It's like buying a Windows PC and installing Linux. The updates would come from Linux, not Windows, and vice versa. You could always go back to the AT&T firmware, just make sure that both firmwares you flash are on the same bootloader version.

But I have always read that OTA updates come from Carrier not from Samsung. Thanks for the info. Maybe AT&T will be out with Nougat by Spring after S8 are out for sale.

Updates do come from the carrier. However, if you flash a different carriers firmware you will start getting updates from the new carrier.

You can pay a 3rd party service to unlock it on contract or not I have done it several times. (I use UnlockUnit for all my devices contract or not get code in like 15min)

When i pop in my t-mobile sim card, the phone does not recognize it or prompt me for a network code or anything ? anyone know of someone or a service to sim unlock the sprint variant ? Thank you
Bump
I'm also trying to figure this out, as I am not able to even connect to T-Mobiles server to trigger the unlock. All that my unlock app does is just sit there with a spinning wheel and say " connecting to server, please wait " , so if I cannot get passed that than I'm screwed cause it's gotta at least prompt me if I want to unlock permanently or temporary. Darn thing just keeps spinning like I'm blocked from even connecting. Can someone who is rooted check to see if their phone will prompt for an unlock or not? Thanks in advance!

If the T-Mobile unlock app is on the Sprint version (Which I doubt) use this site https://www.unlockbase.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/ otherwise you might contact them and find out if they can sim unlock it another way. Or sideload the T-Mobile Unlock app and see if it works that way (I doubt this would work but you never know til you try)

If you are rooted, it can detect it and it will stay on the spinning wheel. Only way I got it to work was to restore to stock no root and it worked (It kept giving me a unlock not available until I bought the unlock service from https://www.unlockbase.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/ )

is the phone paid off in full? no more monthly obligation? if not that's the reason you can't unlock. it's because you don't own the phone sprint does. NO ONE can get a device unlocked from distributor without full payment fulfillment.

I might already be locked being it's a Sprint variant. Boot it up without the sim and if the unlock switch isn't greyed out then flip the switch. After that no sim can relock it

Bootloader is unlockable regardless.
From the way I understand it, if you boot the device with Sprint SIM, it will carrier lock the device. Meaning you will have to wait for Sprint to push updates for OTA.
But I am on Sprint and can confirm you can still unlock and root the device as normal instructions for the device state. And also sideload updates etc with no issue.
