MF3 Sim Unlock Experience

For members who are on the MF3 firmware, what is your experience of Sim unlocking? It seems many are unable to sim unlock. Has anyone successfully sim unlocked, and how have you done it? I'm sure there would be a lot of members who would appreciate the feedback.

i buy my att s4 at full price and requested an unlock code from customer service, they gave me a 10 digit unlock code that worked fine, i am on the f*****ing mf3 firmware... thinking of selling the phone and getting an european version... will see later...
in the past i tested an unlock apk that brute force the unlock code, as it's a 10 digit code you could try that, it will take some hours of key testing, but you will get the code finally and for free don't remember the name of the application have a look on the play store or on aptoide
Cheers

I just did the chat with international care and they gave me the code.

Apparently this works. I haven't tried it though. I have no reason to at the moment.

Ok, seems like an official code from att works. Other methods seem to be mixed. Anyone else?

I took mine to a shop they got paid 25 for to get unlock

I have had no issues with the code AT&T gave me I used a friends T-Mobile card to unlock

[Q] Best way to SIM unlock my SGH-1337 MF3 Phone?

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.

galaxy s4 sgh I337 at&t unlock

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..

i'm pretty sure that I already have a code, and in some reason it still doesn't work.. I'll try it anyway. write now they're on holiday.
But still, does anyone here know about a way to make that cranky menu show up?

it took me directly to the DEBUG SCREEN menu, but I have only 5 options instead of 6. the important option is missing. option number 6, "phone control". is there any direct way to get to that menu? or to make it show the option?

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.

can you explain a little bit please? I am not aware of that method
how much do you think they'll take?

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 region unlock. Unlocked my phone, put in a T-Mobile sim and it didn't asked for a code. Bam unlocked.

guys please explain, i'm a noob. what's region unlock? by the way, my phone is a GSM phone.
also, what's unlocking using a box?
and about that unlockcode247 - can they help me if I already got a code from another source?
I am not from the US and I want to use my phone outside of the USA (the phone was bought in the USA and is AT&T locked).

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?

Jeez...

There is no free method to unlock the phone unless you can get a code from ATT or ebay.

do you recommend anyone for code?

I would not flash any custom ROMs until you get the phone unlocked as you will need a stock Samsung dialler in order to be prompted to enter the unlock code.
I would just look on ebay to find the cheapest unlocker with great feedback.
You may qualify for a free unlock code from AT&T if the phone is locked to AT&T: https://www.att.com/deviceunlock/#/

Sorry didn't realize that.

Have you resolved this? I'm trying to do the same. I am in the US, but I'm not putting the phone BACK on Cricket for another 6 months just to unlock it for TMO.
