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.

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..

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.

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?

I unlocked mine using method 2. You will not have sound until you flash modem back. At least I didn't.
I337 stock, unlocked, rooted

What site offers the cheapest unlocking service?

Anyone?

just flash a firmware with odin yourself for free

It's easy to do, don't pay for that service.... Do it yourself = Free

I had no idea it can work that way? I have a G900T. You are saying if I grab the stock firmware that I already have on my phone and flash it, the locked feature is gone?

1. go to http://www.sammobile.com/firmwares/
2. grab the stock firmware compatible with your phone
3. flash with odin

Im not sure what other roms will work on the G900T but me for instance has a G900I but i use a G900F as it works the same.

You're screwed for now, ATT is locked down until they crack it. Same with Verizon.

Screwed in which way? I could still purchase an unlock code for it and use it on ATT. I would like to avoid that if there is another way though.

If your phone is network locked, then flashing a new ROM will not unlock it, as it is the IMEI that is network locked, not the firmware on the phone.
I got my phone from Vodafone UK and unlocked it the next day using a code from www.unlockunit.com. Cost about $25. I did not have to root / flash the phone, as I simply put in a SIM card from a network other than the one my phone is locked to and the phone asked me for an unlock code.
I have no idea if ATT firmware will stop working once you unlock your phone. but I can confirm that the Vodafone UK firmware on my phone is still working fine.
Hope this helps. If so, please hit thanks button

Has anyone found a cheaper price or way to unlock the tmobile Gs5?every place that I have found wants $30.00 plus dollars.any help will be greatly appreciated. Thanks

I've used this site before:

I don't know if it'll work on all carriers in North America, but you can plug in your details on the site to check before you buy a code.
Took about 4 hours to get my code.

I think you ought to have unlocked before going the U-way. Most unlocker I found utilize the Tmobile unlock app to unlock which is only found on the stock Tmobile firmware. I dunno. Anything is possible. I'm also seeking to unlock mine... I'm outside the US. So I guess I have better chance. Wish there was some free way though.. Goes from $20 to $30 on eBay.. Ain't no cheap unlock these days.

Not really but my guess would be you have to use the stupid unlock app that comes on t-mobile phones. Try www.cellunlocker.net , pretty sure they have the method to unlock using the t-mobile app.

Ok I unlocked 3 T-Mobile s7 edge devices thru unlock base and this is what you have to do
You have to flash the T-Mobile firmware back to your phone thru odin.. Take your sd card out and make sure to click nand erase all while flashing T-Mobile firmware .. You can do this before or after you purchase T-Mobile app unlock.. I did it afterwards
Once you have t mobile firmware on phone use the unlock app to unlock.. Then I flashed the U firmware back but I did NOT do nand erase this time.
My phone is on cricket unlocked and working
Remember to nand erase first or you will get a error on the unlock app because flashing other software such as U screws up the unlock app.. So do a nand erase
You do have to use the unlock app but doing it my way here works perfectly!
Works perfectly.. I done 3 T-Mobile s7 's so far

on the top of the unlock to be able to use the phone in the USA (and we're not offering cleaning service)
which means you won't be able to use in usa
but please contact them about it

I just got unclocked from a seller on ebay. Presently $69.5.. Before unlock my imei was blacklisted. But now imei appears to be clean. Is that how they unlock? Clean imei and then place a call to tmobile for unlock? If there's anyone wanting to unlock, go for esn cleaning 1st (about $20) and call tmobile to unlock your phone and see if they'll do it for free.
