How do I unlock the phone? I currently have Cm11 on it.
I want to ditch rogers (terrible service) so what do I need to do to unlock it?
side note, when I got the phone it was via future-shop warranty and they gave me a fido version and put my rogers sim in it, did they unlock it then?

Since Fido is really owned by Rogers, your Rogers SIM may work in the phone if it was originally locked to Fido. To check whether it's unlocked or not, try putting in a non-compatible SIM (like Bell or Telus) and see whether it prompts you for an unlock code. If it does, you would need to purchase a code online or request one from the carrier. If it wasn't on Android 4.3 prior to the CM11 installation, you may be able to install stock Android 4.1.1 and free unlock. Either way, whether you are free unlocking or using an unlock code, you have to be on a stock ROM for it work. You can check your phone's settings and see what baseband and bootloader versions you have. This will tell us know whether you should flash stock 4.1.1 or 4.3

Baseband is I747MVLUEMK5 bootloader I have no idea, I just used odin to flash CWM.
I'm open to flashing 4.1 to get a free unlock then going back to CM11

I747MVLUEMK5 is ver. 4.3 and you almost certainly have the 4.3 bootloader as well. With this, unfortunately, you can't downgrade to 4.1.1 where the free unlock option is available as any attempt to do this could brick your phone. You would need to request an unlock code from the carrier, if eligible, or purchase one online. There have been reports also that the unlock codes don't work when you are on a custom ROM so if you buy one online and it doesn't work, you will have to flash stock 4.3.

ok, which carrier would I have to talk to, it was a fido phone as mentioned previously. Also is their a possibility I could downgrade to 4.1, or is it a guaranteed brick?

You would need to contact Fido since it was originally on their network. I'm afraid nobody has yet posted a method to allow you successfully downgrade to 4.1.1 and still preserve the free unlock functionality. You could follow some instructions posted in this forum to downgrade to 4.1.1. However, this wouldn't allow you downgrade the bootloader/modem which is required for the unlock.

I found a way to downgrade from 4.3 to 4.1.1 or 4.0.4 stock. (for Bell).
I bought and used Mobile Odin (available on the play store). Anyhow, it flashes the stock rom and not the old bootloaders. Once you're on 4.1.1 or 4.0.4 the problem is that *#197328640# no longer works. Basically when you type that ServiceMode comes up, but all the options are gone. I believe this is because they locked those features on the new bootloader (which is still on the phone after the Mobile Odin downgrade...)
Unlocking this phone has become a major pain in the ass.

You are quite right. Sam and the networks are winning this time. You can indeed use Mobile Odin to downgrade the system (ROM). However, there hasn't been any reports of a successful downgrade of the bootloader. Therefore, even if you downgrade without bricking the phone, you can't free unlock. Tough but you will need a carrier unlock code.
Hiya,
I currently have a Samsung Galaxy S3 locked to Bell, and I have installed Cyanogenmod 11.
I'd like to unlock it and give it to a friend.
My questions are:
1. If I unlock this phone, will it work with Zoomer Mobile? It's a subsidiary of Rogers. I would imagine it would work, I just want to make sure.
2. I've read somewhere that Cyanogenmod causes problems with unlocking, is that true? Will I have to go back to stock firmware in order to unlock it, then go back to CM11?
3. I can't seem to find any information about unlocking through Cyanogenmod... anyone have a link to a guide of some sort?
Thanks in advance for any help!
am pretty sure you have to be on stock firmware to use free unlock method. will try to search around with for more info

Tell us the bootloader version on your phone.
Once unlocked, it will run on all carriers except wind and mobilicity.

Thanks, thats great to know! My bootloader version is I747MVLUEMK5.
Thanks for all the links mrrocketdog, looks like everything I need to start unlocking!
Since you are on the MK5 bootloader, you will have to flash back to stock, purchase an unlock code, unlock the phone, and flash back to your custom ROM.

Which version of stock, though? I can't remember what the phone came with since it was so long ago... I think it was something like 4.1 , but I'm not sure. Since I've since updated to 4.3/4.4, I'm also worried about bricking my device, because I've heard that flashing earlier roms with newer bootloaders can do that.
Which version of stock should I go with then? Thanks in advance!
Confirm that you have an i747m with mk5 bootloader and baseband. This can be done by using the Play app called Samsung Phone Info.
The stock i747m firmware is available on sammobile.com. Just search for the Bell sgh-i747m 4.3 ROM. You can flash it using Odin. Do NOT check anything except auto reboot and F.reset time. I recommend using Odin 3.07 and backing up your important data to your computer as flashing with Odin will wipe your phone.
I have an AT&T Galaxy S3 (Model SGH-i747) that I have unlocked and am using on Tmobile. Since it was originally an AT&T device, am I able to use Odin and simply replace the ROM with the Tmobile version (t999 I believe)? The phone is totally stock with the exception of being unlocked with a code from AT&T. It is running Android 4.1.2 Kernel Version 3.0.31-1300972. I downloaded a ROM for the Tmobile t999 with Android 4.3 and when I tried to install it Odin gave me an error: Secure check fail sbl2. I really don't like the AT&T boot screen and AT&T bloatware, and I'd like to run the factory Tmobile setup. Is this doable or are the 2 models of Galaxy S3 different enough to prevent it?
Flashing a stock T999 ROM will also try to flash a bootloader and modem that are not compatible with your i747 and may hard brick your phone.
Thank you, I appreciate the help. Do you know what options are available if I want to get rid of the AT&T boot screen and bloatware (Specifically the AT&T contacts book) while maintaining all the functionality of the device? I have been searching around on this site and google and I've been having a hard time finding information specific to this situation.
You could try a custom ROM but before flashing anything, it's a good idea to verify your bootloader and modem version.
If you are running an old bootloader and modem, you'll have to decide if you want to upgrade to use the latest custom ROMs or stick with your current bootloader and modem.
I Used To Own A Tmobile S3 Which I Enjoyed Using Custom Roms Like Cm 12, LiquidSmooth 4.1 And Pac Rom Just To Name A Few And The Lcd Broke . So One Of My Friend Is Selling Me A Used At&t S3 On Stock 4.4.2 For Quite Cheap. But My Problem Is ( Correct Me If Im Wrong) I Think I Read An Article Stating That You Cannot Use Custom Roms On S3s On Stock 4.4.2 Or It Will Brick It . Is This Correct ?

The bootloader is not locked on the AT&T S3 (I747). You can use Odin to flash a custom recovery and flash any ROMs for d2att/d2lte you want. No unlocking required. It is a pretty modder friendly phone.
The thing you cannot do on the newer bootloaders is downgrade the bootloader. Attempts to downgrade anything beyond the 4.3 bootloader will result in a hard brick. This also prevents you from using the free sim unlocking method because it involves a firmware downgrade to 4.1. If you need to sim unlock the phone to use it on a different network you'll have to get a code from AT&T (they should provide one since a phone this old just about has to be off contract) or purchase one from a third party.

I concur with @jason2678
I have an AT&T SGS3 (d2att/i747) that is on the NE4 bootloader and modem (4.4.2) and am running CM11 atm. As a matter of fact, none of the CM or AOSP roms since late in 4.4.2 development will run unless you are on one of the 4.4.2 bootloaders (NE4, NJ1, NJ2)
What you stated, quoted above, is true for the Verizon SGS3 (d2vzw/i535).

It appears that you have an NE4/Android4.4.2/KitKat rom installed over 4.3 bootloader and modem. I have seen several custom TouchWiz roms that run fine with this setup as long as one of a couple of custom kernels were installed. CM and AOSP roms will also run in this condition. BUT, from what I have read you will not be able to use the unlock codes. My reading indicates that you must be on complete stock ROM for the code to work, including stock recovery instead of CWM. ALSO, what I have read says that you only gt five attempts before the code becomes invalid.
I don't know why your phone is not asking for the unlock code, unless it has already been carrier unlocked. Even thouhg it is not asking for the code, does it function as it should?
Frequently the service modes do not work on custom roms, even TW based ones, because they are not using the stock dialers. I have also seen it reported that some were disabled with the 4.3 update and others in more recent updates.
Proceed carefully.
You may be able to enter the unlock code if the phone is running a stock dialler with a matching bootloader and modem combination.

Thanks for respond
I had this phone since 3 years ago (new from ATT) and rooted stock rom with CWM 6.0.4.7 recovery touch . and I remember that I could unlocked through SERVICE MODE when I was overseas. ( sure I had used this phone with Other carrier) about 1 year ago I put this phone in my drawer I did factory reset and installed Stock firmware and update OTA to 4.3.
Last week I want to use this phone with Tmobile SIM but got Phone Not Allowed MM#6 message . The rom was still 4.3, Contact AT&T and got Unlock code.
but this phone didn't ask for unlock code entry option and still 4.3 , tried the whole weekend with service mode and upgrade to 4.4.2 via CWM recovery.
and still no luck
With your suggestion , it means that I don't have choice to downgrade back to 4.3 rom same with my bootloader and baseband? I heard we can't downgrade if we already in 4.4.2 , is that true?
But I still use stock recovery from CWM.
Before I proceed with replacing with stock recovery, is the stock recovery have to be 4.3 stock recovery or any version for S3? do I need to use odin to change to stock recovery?
if you have good link please help?
Thanks again

Stock dialer means the entire Rom must be replaced to match my bootloader and modem combination or just replace the dialer in my case and still use 4.4.2?
Appreciated if you can help, thanks
Stock dialler requires a stock Samsung kernel.
From what I am seeing, you are on the 4.3 bootloader and modem. As I said before, there are custom TouchWiz 4.4.2 Roms that will run on the 4.3 bootloader and modem. Changing to a 4.3 rom, stock or otherwise, therefore would not be downgrading your bootloader and modem.
What rom are you on?
Some of the custom TouchWiz roms use dialers from the S5, therefore not stock for the S3.
Some of the custom TouchWiz Roms use the stock kernel, some use a custom kernel.
Did you flash a custom kernel?
What is your kernel version? (check under Settings > About Phone)
With the answers to the questions I asked, audit13 and I may be able to give more definite guidance. It could be as simple as flashing the stock kernel and a stock dialer. But, I can't tell at the moment.

Are you saying you unlocked it before? If so it should still be unlocked. Flashing/wiping won't affect that, so it's pretty much a permanent thing. If so, maybe the Sim card you're using is an older one? they don't always work on tmobiles networks.

(yes I remember for sure I have used this cell phone overseas couple times and the way I unlocked through service mode. Way before AT&T OTA update since new)
I have weird situation that make me wondering if I had unlocked my S3 since message
"PHONE NOT ALLOWED MM#6" comes up if I use any other carrier beside AT&T
Per http://forum.xda-developers.com/showthread.php?t=2789917
thanks to OP
I just managed to change my bootloader to I747UCUFNE4 and also my baseband version to I747UCUFNE4
I still keep my CWM 6.0.4.7 recovery touch
I have Flashed with countless other rom such below:
I747UCUFNE4_Stock_Rooted_Odex.zip
I747UCUFNE4_Stock_Rooted_Deodex_3-31-15.zip
I747UCUFNE4_Stock_Rooted_3-31-15.zip
and even custom rom without any success
This was happened with my S3 after flash.
if I flashed with inserted active SIM Card (T Mobile or foreign SIM Card)
I will see PHONE NOT ALLOWED MM#6 after reboot
if I flashed without any SIM Card inserted after reboot :
- inserted foreign sim card and reboot again
I will have AT&T as roaming provider and for about few seconds received text message about fee from SIM issuer roaming to AT&T so means My S3 is unlocked...
(no... not so much!!!) in few minute I will have "PHONE NOT ALLOWED MM#6" and phone is useless as emergency only.
- inserted T-Mobile Sim Card and reboot again it shows "PHONE NOT ALLOWED MM#6" immediately
My Kernel Version :
3.4.0-1514807

So you are not getting asked enter a network unlock code when running a stock rom with a foreign sim?
Does your provider use aws frequencies? The i747 does not natively support T-Mobile aws frequencies.

Hey I recently got an S 3 on the T-Mobile network, and need to switch over to Verizon. I've looked around on here for different SIM unlocking methods, and just had a few questions:
1 can I just flash a Verizon ROM onto the phone in order to use my Verizon SIM card on it? (Something tells me this is a no)
2 if the above is not possible, and I have to get an unlock code, will I still be able to use a cyanogenmod ROM, or would I have to revert back to a stock ROM?
Thanks for your patience! Sorry if this a dumb question or if I posted in the wrong place!
I'm running:
TWRP 2.8.6.0
CM 12.1 d2tmo
SGH -T999L
If the phone is running a 4.1.1 or 4.1.2 bootloader, you could be flashed to stock 4.1.1 and sim unlocked using the free method. After unlocking, I would run ota updates until, the phone is running the latest stock rom. Once updated, I would install twrp and flash a stock rom.
If the phone is running a 4.3 or newer bootloader, it would be best to be running a stock rom in order to enter the unlock code.
