You need to put a SIM chip in your phone from a different carrier. When you restart the phone it will ask for the unlock code. Enter the code and your phone should then work with any SIM inserted.

If you don't have a SIM from another carrier you can root your phone and install Galaxy S Unlocker from the market for free. Once you do open it up and click on unlock. Your phone will now be unlocked.

You can then check that it is unlocked by opening your dialer and entering *#7465625#

If you mean sim unlock,all I did was call and ask for the unlock code,as long as your account is in good standing,shouldn't be an issue.

I sent them a text msg asking for it. 3 days later arrived in my email
Unlocking Xfinity S8+
Your post says they gave you the code in response to a text. Did you already have the OEM unlock opition visible in dev options? I don't even have the prompt... I wiped cache part and did factory reset, as someone suggested, but it did not appear after that (contrary to what this person said they'd experienced). So, did you unlock with some specific dial code? or did your settings>dev options have an OEM unlock prompt?

You have confused SIM (carrier) unlock with bootloader unlock. You can not unlock the bootloader on any US (snapdragon) version of the S8 and S8+.
On the other hand, you can SIM unlock with the code that Xfinity Mobile gave you. Turn off the phone, and replace the XM SIM with one from a different carrier. Boot the phone, and your device will ask for SIM unlock code.

Hi, and about the z3x Samsung tool, is possible to unlock with that program?
I know its more complicated, i have been searching and reading and found that.
I try a unlock code without success, now ask me the puk code , and the company refund my money.
And now what's my chances to unlock it?

I'm not familiar with the Z3X tool. If you're trying to carrier/SIM unlock your device, your best and possibly only option is to get your carrier to unlock it.
If you are trying to unlock your bootloader, it's not possible.

I think Xfinity is CDMA, so this is the only viable option you have.

Is there a root and custom recovery for J3 Luna Pro SM-S337TL?

I'm using Wal-Mart's Family Mobile which runs on T-Mobile's network. Phone is running 7.0 Marshmallow. Even though this phone has 16GB of onboard storage with a micro SD card slot, I don't like how they lock the permissions of Gapps bloatware and wouldn't mind the opportunity to free up additional storage space. Has anybody built a custom recovery yet for this model of the J3?
Update
The bootloader appears to be unlocked, though the FRP lock is enabled. In previous attempts to install custom recovery programs, FRP locks have kept Odin from flashing anything to the phone.
Any advice would be appreciated. Trying not to add a brick to my collection.
how did you do it?
I happened to buy the same model for simple mobile.
I am wondering about the same thing.
It sounds like you were able to gain root.
How did you do that?

disabling frp is simple remove all google and samsung accounts from your device then reboot. it will say frp is off in download mode. but if it says secure check failed your bootloader is locked. and by what your saying your using the j3 prime which is the same device i have and i been trying to root it ever since june. the bootloader is locked and it isnt unlockable. even oem unlock is missing. if you want root and twrp you need to get the j3 prime (sm-j327u) directly from samsung. it is unlocked for all carriers and has oem unlock in developer options.
I got my hands on this device and i would like to network/sim unlock it since its from usa and i am located at Greece.
download mode and recovery both accessible but not fastboot one. No unlock oem option on developer options.
Tried pushing a custom recovery with adb no luck and cant find a stock rom anywhere.
Only option i found is a software called samkeytwo seems a mix of bit shaddy and bit legit requires a payment to do the job.
Personally if a one time payment will do the job its fine with me so pretty much my question is if anyone here have used this and can tell if its working or not?
so my friend on the states has got the same phone and went to a verizon store since he was a costumer of verizon carrier he handed the phone over to an employee and after a short time around 5 minutes he got the phone handed over back to him with a verizon network sim on it working.
talking over with him to undertand how he did it i found out the following. Oem unlock is visible in his developer settings but grayed out so he cannot turn it of or on.
The phone instead of the tracfone logo has verizon when boots up
The phone Baseband version is G8998-00164-1710262031 which reffers to google pixel 2 verizon ?!?!?!!? (his device is still the actual luna j3 pro)
Finally his phone is running android version 8.1 instead of the 7.0!!!
What sorcery has took place at this verizon store?
Little lgnomes perhaps, I try to catch the little buggers every night but unfortunately they are too fast for me
my phone says pin blocked when the sim card is in.
it says google account locked when the sim card is out
does anyone know how to fix this?

T-Mobile bootloader Unlock Help

I have an unlocked T-Mobile One plus 7 pro connected to fastboot. I can run the command fastboot devices and it shows up fine. Says I need an unlock token to unlock the bootloader. Can someone advise me on what to do next or how to get the unlock token? Thank you
You are sim unlocked, right? Just making sure.. You do not need the unlock token, unless you plan to stay on the t-mobile OOS version. There's a guide right here to convert your phone to the international OOS, and thus unlock bootloader with "fastboot oem unlock"

If you're planning to stick with the t-mobile oos, can you, or any with a rooted t-mobile oos care to disclose if RCS continues to work? Thanks.
It says I need a decryption key to access the first link you posted? Any idea
Well, I had to request an unlock code and get the unlock token in order to unlock the bootloader in the first place, then I could root, twrp, and port to the international rom
Now I cant get the msm tool to open... It says it's been opened but it's not opening
@akinkoff85 , it takes a full 7 days to get the unlock_code.bin , but I think it's worth the wait.

T-Mobile Bootloader/Sim unlock Bypass..

I'm shocked there is absolutely no discussion on the new method that just launced. Due to the lack of activity, it's not made clear if the bootloader unlock method unlocks the sim card as well.. I don't even know if the method is worth taking or has any significant issues in the longrun..
Convert to international and it bypasses it
Edit:
Nevermind didn't read it correctly
If you're talking about the q upgrade to get bootloader unlocked. I'm kind of surprised too.
I unlocked my bootloader via that method and it did not sim unlock my op7p. I dropped an at&t sim and it told me the phone is network locked and to use the Tmo unlock app.
Any method of getting it Sim unlocked if you are outside of the US?

None that I know of if you buy a network locked version like the GM1915 from TMobile. Have to go through the carrier for SIM unlock on those.
The guy that started the tmo to international conversion thread said it's possible, but complicated and would be release later. Hope they get it out soon.
The Q unlocks the bootloader but the GSM SIM is still locked. I tried this command and got this response
./fastboot erase modemst2
Erasing 'modemst2' FAILED (remote: 'Erase is not allowed for Critical Partitions
')
./fastboot reboot
Rebooting OKAY [ 0.002s]
Would be grateful to find someone with useful info on how to sim unlock this phone.
Thanks
man, would love to find a way to sim unlock this outside the US. sucks
If you have t-mobile version there are 2 guys on guide thread that unlock the phone through the t-mobile app. If your using t-mobile outside the carrier you will have to pay to a 3er party service eBay haves them
Do you know of any 3rd party service that can do this? Please let me know, thanks

Refer to my thread (https://forum.xda-developers.com/oneplus-7-pro/how-to/t-mobile-op7-pro-sim-unlock-t3957662) if you need your T-Mobile OP7 Pro SIM unlocked.
The issue is that I'm outside US. I bought my phone on eBay and it had outstanding balance. The seller didn't provide me with the information you need for unlocking.

No, these commands are for the dangerous ability to flash & erase criticals like modem.
The code to unlock BL is:
fastboot oem unlock
(Erases all data)
---------- Post added at 08:08 AM ---------- Previous post was at 07:53 AM ----------
I dunno if BL can be downgraded bc OP7P starts on android 9 rom which has security patches which prevent flashing to modem.
Found this thread for a different phone which has the same issue you guys are having:
https://forum.xda-developers.com/essential-phone/help/failed-remote-flashing-allowed-modem-t3924591
If BL can be modified, the perhaps you can erase/flash Modemst1 & 2. If anyone knows of someone who tinkers with BL, bring them here :fingers-crossed:

Ok when you flash the msm, it locks the bootloader so you gotta use the bin file that you got.to unlock the bootloader from fastboot then it will be greyed out.

Yes but you need to have your device sim unlocked first before you apply. You can get that through TMobile. Also check out the thread of the person helping with unlocking the sim.

i cant get the unlock code from fastboot. maybe there is a workaround like with the op7p where oneplus released a beta with an unlocked bootloader. i have the patched msm.exe from then but it wont load the .ops file.
is it possible that if i flash the eu or international .ops file it will allow me to unlock the bootloader?
Not that I know of yet. If you can't get the unlock code, most likely you're not sim unlocked.

just spoke with tmobile and they said its not blocked and ready to be activated. also that without the tmobile unlock app i would have to test it with a new sim card. think it might be a problem if someone unlocked then factory reset before they sold it?
i read the post before making my own. i dont have the previous owners name or phone number.
also i looked up tforce on twitter but there's only 1 person with that @ and they dont seem like theyre active

I got the unlock code from fastboot, but when going to enter it on the OnePlus Site it says it is invalid because it is not a 64 digit unlock code. ????
I have an unlocked EU model IN2023 from Amazon UK and my OEM unlock button is greyed out. I'm so confused
I see this is an older thread, but I have the same problem with Nord CE; Oneplus support is not of any help (they just spam me with "we don't help with unlocking the bootloader, it's a security problem").
Anyone found a workaround?
