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.
My device:
At&t Galaxy S4 (US)
4.2.2 (Google Play Version)
SGH-i337
Baseband: XXXXXXXXMF3
From What I understand, it can't be unlocked for t-mobile and whatnot. I've been searching around today for a couple hours, and doesn't look like there is a working method anymore
When trying through *#0011#, pressing "1" doesn't bring up a second menu; the menu stays the same.
Unlock codes won't work because device is Region locked (I'm in the US)...
That is what I found while searching around today...
Any advice would help. I can't for the life of me find a thread that fits my description. They're all just general gs4 unlock guides from months ago...
Looking around I couldn't find someone actually post this, so I asked. Sorry if its a repeat?
So have you acquired the unlock code to know they don't work.

Rooting isn't going to make any difference, but give it a try if it makes you feel better.
If you have a ATT phone you want Sim unlocked than the code you get from ATT will work if you want to use it with
T-mobile. (Same US region)
There is an app on playstore that will region unlock the phone but it is not a Sim unlock app.

I did the menu unlock and it was successful for me when I was on MDL.
I'm MF3 now and because I did it before it is permanently Sim unlocked.
Region lock away v1.0 on playstore.if the playstore don't bring it up than Google search it.
sent from a I337 MF3 S4
Yeah, I found out about that one...
It's not a SIM unlock though... So there isn't a way for me to unlock it yet that I've found.
You are rather confusing to me cause the sim and region unlock are the only two things you can unlock on this phone.if you have been talking about unlocking the bootloader than your heading is correct.
" NO UNLOCK FOR S4 "
now even if your bootloader was unlocked it has nothing to do with your sim or region and the ability to use it on a network that's in the same region as your phone currently.

Sorry not trying to sound confusing.
I'm trying to unlock my mf3 Galaxy s4 for t-mobile. in the US. Don't need region unlock. (unless this makes it work on tmobile in the US?)
I've trying unlocking the phone through ATT customer service, but they can't/won't.
That's all I know so far...
U mentioned something about the region.if your phone is the i337 ATT branded/model phone keep calling ATT and lie to them that you need the unlock code for your phone cause you plan on going out of the country on the coolest vacation ever and it is cheaper for you to acquire a foreign sim card and you need the code for the sim to work.

I factory unlock phones as kind of a side job and all AT&T servers have changed their unlocking so it's extremely hard if not impossible to get the unlock through AT&T. You can still get a manufacturer unlock but it's pricey.
Ok I'm not understanding this... So if I get Region Unlock from the google play store will it make me be able to use any SIM card inside US?
And also where can I find a manufacture unlock?
And If all else fails is there alternate options?

Its just a region unlock you still have to sim unlock it.
I understand now why its so hard for you to just call ATT for the unlock code cause its not your phone.there is no nifty little trick anymore . someone mentioned a way to mod the system to get the service menu back but it is work.GOOGLE/SEARCH

No, i tried calling att several times. They keep telling me I need to have it on contract for 6 months before I can have it unlocked. I dont have that time...

I think if all else fails, you can just buy the unlock code.
I've been reading the unlock thread and it seems you can get "Unlock your Galaxy S4" by unlockunit from the play store to unlock it.
Haven't tried it personally as my phone is in the mail...but I'm hoping it is a non MF3 and easy to unlock phone.
A lot to hope for, I know

Hey there, I have a samsung galaxy s4 sgh-i337 locked to at&t.
I bought an unlocking code from an ebay user.
it doesn't unlock my phone, it writes: "unlock request unsuccesful". I tried to use the defreeze code and then again the network code, still nothing.
I was referred to a guide that suppose to show me the "service mode menu", by entering *#0011# . so service mode goes on when i put that number in the dial pad, but then I suppose to do 'menu key'->'back'->'menu key'->'key input'->'1', but after I do that nothing happens, the service mode menu with all the options doesn't pop up, it stays in the same page of the service mode. somewhere down on the ServiceMode page it writes "Service:Limited". what should I do?
Talk with an at&t rep or chat online and indicate that you will be traveling and want to use this phone there and they'll give u a unlock code..

Someone... Help.. please
no Mega genius here that can solve my problem?
same boat here man, this is a new problem since not everyone has 4.3 yet. Att won't even give me the unlock code since they changed eligibility few months ago to "only off contract or fulfilled contract phones." I've read one person saying the eBay unlock code didnt work on 4.3 either. And the only success i've heard is another post here on XDA saying they unlocked 4.3 using the regionlockaway app, but they apparently Odin flashed 4.2.2, did the regionlockaway while the phone had no sound/wifi etc., then Odin flashed 4.3(locked again), then flashed 4.2.2 odin again, regionlockaway'ed, then odin'ed 4.3 again and the unlock stayed. That sounds ridiculous and is not an exact science.
So i'm done with At&t's phone slavery and switching to T-mobile on a nexus till the Xperia Z1 is out. I thought this was the future.

Take your phone to one of the shops which do unlocking using a box. It is possible to do it.

If you have another $20.50 go to Myhoian's website it's unlockcode247.com it'll take about a full day or over 12 hours usually but not longer than that he's never failed to unlock any of my phones.

I used Cellunlocker.net and it was done in 24hrs. It did cost $29.99. Since I was on MK2 the only way to get it unlocked for free was through my carrier and they would not unlock.

My carrier said I was qualified to do the unlock. How are these services? Paying that much money on a limb sounds sketchy and most endorsers seem to be part of the sketchiness. Anyone else have experience using the only sites?

I337 stock, unlocked, rooted
Hi,
My current phone Samsung S4 SGHI1337 with software version ending MF3 is not eligible for unlock until the contract expires with AT&T. I was told that this phone with the IMEI number can be unlocked but I have to make sure once it's unlocked, AT&T will still service this unlocked phone.
I don't know what this all means. I need to take this phone with me abroad. I don't want to pay for expensive international roaming with a locked phone.
Also, has anyone used cellunlocker with positive experience?
Thank you.
I have used them, and it worked great on my i337m here in Canada. 25 bucks, got the code a couple hours later, threw it in with a non-Rogers SIM, and boom, it worked. HOWEVER, I am using the i337m from Canada, not the i337 from AT&T, so YMMV./
I unlocked my i337 by flashing the MDL modem file using the instructions for the dial codes then flashing current build modem back worked and did not trip knox
Thanks...but technically challenged.

No, I have not. Not sure how to do that either. I read some of the posts here, but still have not a clear clue. If you could point me to a more step by step post, I'd very much appreciate it. :cyclops::cyclops::cyclops::cyclops:
FYI - my current phone does not have international roaming with AT&T. I have it disabled. Would this matter when it comes to regionlock? Can you region unlock EU Zone? I just want to be able to take the phone with me to Europe and insert the local SIM so that I don't get outrageous charge on international roaming. I do text a lot while abroad.
More Confused Than Ever
I am the OP in this thread. I am more confused than ever.
I just used the code *#12580*369# and found that the RF Cal is 20131114 Date of Manufacture
I then used *#1234# and found out that all the AP,CP,CS ended with MK2. But on the phone box, the S/W version ended in MF3. So I don't know if I have MF3 or MK2 firmware version.
When I use the code *#197328640#. I cannot see the #6 Network Unlock screen. So I guess it's hidden from me.
Sorry for all these questions. I am a newbie at this.

Looks like you have mk2 firmware. Your phone came with mf3 but you must have taken an ota update to mk2. That's pretty normal.
I got my ATT S4 wet and could not recover it so I am needing to get a used replacement on ebay. Will any "unlocked" S4 work on my ATT contract? My old S4 had MDB firmware when I purchased it so it was easy to use Custom ROMs and TWRP. With replacement phone I again want to use TWRP recovery and Flash ROMs. I keep seeing talk about how unlocked Verizon phone may or may not work with ATT and do not fully understand the differences in Carriers . Any info is appreciated.
Thanks
If it's sim unlocked it should work on at&t. But you'll probably not get a phone with mdb or mdl firmware and therefore will not be able to use twrp or cwm.

Thanks for reply. I know it going to about impossible to find MDB again. I have emailed each seller of a phone am looking at and no MDB or MDL yet. Hopefully I will find an XDA guy with old S4 at some point that has used Custom ROMs and still on MDB or MDL and he can ODIN back to old Stock.
Ron,
keep me in mind here or PM since mods may not let a buying thread go on long
I have an MDL S4 ATT 32gb, and obviously by my member info, rooted and with TWRP 2.5.0.2--the best recovery for us. Perfect condition and many xtras plus a 64gb Sammy sdcard.
I may, due to my son and his wife's pushing, get the iPhone 6 plus. Flashing is winding down for me and they want us all on the iPhone "ecosystem" (continuity). And time for a change.
Wasn't sure I was ready to part with the S4, too damn nice of a phone.
Since I am now subscribed to this thread I wil see your posts as long as thread is open. I need to do some quick decision making.
