If i root device and flash international version of rom will i be able to use any sim on it? or is there any other free or paid ways to unlock it?
yes there are paid ways to unlock it.
I haven't been able to find any way to unlock it
Bumping this. I tried an international ROM and I just keep getting the "no sim" icon

I was told that if i root the phone and then install busybox and Galaxy_S App that my phone would be unlocked? would this work for att and when i go to brazil?
For a while there was galaxy unlock app that worked for me and others (and not for some). It only required root to use and it would spit out your unlock code.

I've used that app on a friends phone who went out of the country. It couldn't find the unlock code, but I used the second option and it patched a folder. It worked great. Unlocked in seconds. VERY EASY.

Just call T-Mobile and ask for a code?
So what's the way to unlock it? Thanks!

You get an unlock code (from t-mobile or hacked) put a foreign sim card (at&t works) reboot phone. It'll ask for code. You put the code in and it's unlocked.
What is the way hacked? The phone has no service atm
yes it is,just follow the instructions carefully
No you need to unlock it ,If you go Brazil or other country means you need to unlock your samsung Vibrant Phone,After unlock it use with any GSM Network Sim card.I haven't used that Apps Unlocking,You can better get the unlock code from the site
Theunlockarena.com/samsung/rs13wp8/ and unlock SAMSUNG VIBRANT.
Get SGS Unlock from the Market. The free one might work (for me it didn't), but the one that is not free got the job done.
simply can i booot my phone? I tried going by instruction, at SE website it did give me the code, but it got stuck where it says find the driver and sE says it cant be boooted. so im wondering if that is true meaning there is no other way for now?1
how about if i pay to one of these unlocking websites and try agian?!
Root with gingerbreak. Unlock sim with cellphoneunlocker.net. Do not unlock bootloader as there isnt any reason to yet. Just my 2 cents

I have Galaxy S4 SGH-I337M (Fido)
Andriod Version : 4.2.2
Baseband : I337MVLUAMG1
Build : JDQ39.I337MVLUAMG1
How do I unlock the sim? I would like to use Bell sim later on.....
please don't bring up the idea of buying unlock code....
Buy yourself an unlock code and save a lot of headache. Otherwises there's something I think they call The Google, our something like that. I hear you can find all sorts of stuff with it. I'd probably try something like "sim unlock s4 xda"
We have Canadian i377m.
WE ARE FREE TO DO WHAT EVER WE WANT WITH OUR PHONES. It's like having a Google edition
And a simple yes. YOU Can Downgrade To What is the oldest firmware, so you can free unlock

Instructions should be free once an unlock code is purchased!
Anyway, the process is pretty simple.
Get an unlock code and then turn the phone on with a non-accepted SIM card. If the phone is locked, it'll then request the unlock code from there. If any company charges for those instructions, they're ripping people off.

Buy an unlock code. I've tried the free method and it FUBARed my phone. Unlock codes wouldn't work even after trying to undo the free unlock. The only thing that was able to unlock my phone was a paid USB unlock method.
$15 is not that expensive compared to network bricking your S4 with an unreliable free method.
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.

You mind letting me know what you did, so I can copy your steps?
I'd much rather do that than following the generic guides...

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...
Every other way doesnt work for me...

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

I just got my U.S. Cellular s5 (G900R4) a couple days ago on Craigslist for $175 and I've been enjoying it thus far. I rooted it with towelroot just fine, but I'm a bit confused about the state of my bootloader. Is it already unlocked, or do I need to run some program to unlock it? I searched on Google and xda for a while and found nothing about this. I guess the U.S. Cellular model just isn't very popular. I just want to be sure so I can safely flash TWRP and flash some roms without ending up with a borked phone. TouchWiz is so slow compared to my Nexus 5 :/

We don't hear a lot about you USC guys. Given that all of the USC Motorolas, Sony, Samsung, et cetera that I have seen in the past have had locked bootloaders.. I'd bet that yours is too. And I'm confident that a forum search would confirm whether USC continues to lock bootloaders.
I don't have a 900R4 to test, but this dialer code may work -
Dial *#*#7378423#*#*
Then choose Service Info > Configuration
If it says:
Bootloader unlock allowed: Yes <---- this means that your bootloader is locked
Bootloader unlocked: Yes <---- this means that your bootloader is unlocked
I rather doubt that you will find any program to unlock the 900R4 bootloader anytime soon. But you can probably follow the Verizon tutorial for using Safestrap to virtual instance of a custom ROM or TWRP.
.
My phone isn't active on USC yet, so I can't dial anything. I'm just going to assume that I am locked. Safestrap seems like my best option. Thanks!

Doesn't have to be activated to use the dial code, just open up the dialer and enter the code listed. Good luck.
