If it was brought from a carrier (ATT, Tmobile etc) and you have completed the contract or paid ETF or paid phone in full, you can contact the carrier.
They will unlock for free.

I did contact them but im still under contract, now i looked up a seller on ebay but it says that if he gives me a code it probably wont ork because i rooted it, im still on the original room i only flashed the kernel and used towelroot to root it, is it true that it wont work the unlock code?

No. If you are on stock ROM, code should work.
I had phone in the same state (running kitkat, rooted with towelroot). When I completd/terminated my contract, got the code from ATT and it worked.
You can only try the code few times. After that phone will lock to the operator and no code will work after that (even if right one).
So make sure the ebay seller is giving you the right code for your IMEI.
If its under contract, even 3rd party seller may not be able to unlock. Check with them before you buy.

ATT has given me the unlock code in years gone by, even when I didn't have the phone paid off. I explained that I need local SIM-as-you-go accounts when traveling for work. (true BTW)

[Q] Galaxy s6 edge sim unlock problem, please help

So i bought this sgs6 edge device from telus canada.
brought it back home, had the unlock code (also bought from telus and several sim free unlocking sites) and the device just keep poping up the same massage: "network unlock code unsuccessful"
tried every guide on youtube and on any forum i found online, nothing helped.
All the methods, through the dailer, everything.
Can someone please guide me how to sucssesfuly unlock my device?
Many thanks!
Sounds like you got a bad code. You should request a refund and buy one from another vendor. Be careful entering the code too many times. After 10 (I believe) it locks and you can never sim unlock it.

Is the phone paid in full?
The only reason I ask is that I bought an AT&T Nexus 6 shortly after they were released. That's the only Nexus not sim unlocked and my condition on purchase was for the seller to unlock it. We met at an AT&T store, I popped in my Verizon sim and the seller gave me the code. I tried it a few times but the code kept coming back unsuccessful. He called AT&T for the correct code and lady told him she couldn't give it to him because it wasn't paid off (although they had previously given it to him). After some conversation, he eventually gave them his CC # to pay it off. They then provided the exact same code. I hesitantly tried it again and it worked.
I also recently learned that the T-Mobile S6 Edge doesn't take an unlock code at all. It must be unlocked by T-Mobile or it can't be unlocked at all.
Perhaps the carrier is somehow keeping it locked front their end?

So you simply say i have to call them and fully pay it off, so they would relese some sort of lock they have on the device and then i would be able to open it with the exact same code?
If thats true thats might work. I'll try it and update for any changes. Many thanks!
Hey man, my phone is fully paid in. I talked to telus and they said the sim unlock is aprooved in thier computers so what is the problem?

Options for Unlocking AT&T Samsung Galaxy S5 GM-900A

Hey Everyone,
I need assistance with unlocking my smartphone; it's an AT&T Samsung Galaxy S5 GM-900A. I did a little research on the internet and it's my understanding that unlocking a Samsung smartphone linked with AT&T is a bit more difficult than it already is with other companies. I also saw a lot of sites that offer "unlocking" services for a certain price. Before I decide to do that, I wanted to know if there were any others options or which site is most reliable. From what I've seen and read, it seems that this forum is the best option for seeing if this is possible. Appreciate any assistance you guys can offer.
I am not familiar with unlock sites but have heard mixed reviews on them. Those sites can only unlock the sim card, not the boot loader. Just thought I would put that out there since you didn't specify what kind if unlock you were looking for. I recently submitted a sim unlock through AT&T for my s5 since I am out of contract.

Unfortunately, mine is still under contract but I would like to unlock my smartphone so it can be used with another carrier. This is the type of unlock service those sites are saying they can provide, right? I've also read and heard mixed reviews on the internet, which is why I came here in hopes that I can get additional info on this. Thanks for your prompt response.
Just use att they will unlock your sim

What's the difference between that and sim unlocking? Any disadvantages on just having the sim unlocked and not the bootloader?

Thank you. I checked it out and it doesn't seem to support "Galaxy S5 SM G900A"; the only thing close to that is "Galaxy S5 SM G900F". Appreciate it if you can suggest another site.

Call ATT. New laws made all carriers be (generally) required to unlock their SIMS not bootloaders under some conditions. see link https://www.fcc.gov/consumers/guides/cell-phone-unlocking-faqs
If u are under contract they will make u pay but u then meanwhile u can use another carrier. Here is a link to an unlock service. https://www.doctorsim.com/us-en/unlock-phone/samsung/
Good Luck!

They serve entirely different purposes. Sim chooses carrier (ATT,etc). Bootloader chooses what will be started when phone is booted ie system(rom), recovery(TWRP etc), bootloader itself. Bootloader unlock means changes can be made to what will start under different boot requests. No disadvantages to just unlocking sim, often used for foreign travel where your regular sim will not connect. Many times carrier will unlock SIM LATE in contract for foreign travel reasons.

Are you under contract via a next plan thru at&t? If you are planning to unlock to switch carriers I imagine you want to end service with at&t. If so they will want you to pay for the phone in full or return the phone. If you don't pay & keep the phone I'm pretty sure they blackball the imei so it can't be used by any carrier. So what's your end goal here?

Yes, I'm under a contract that has been suspended and told them that I am currently not able to pay but also am not able to get another phone due to financial reasons. They said they understood my situation but cannot unlock my phone due to the contract and that once I am able to pay, they will provide me the unlock code if I still want it or wish to continue using their services. I guess what my end goal is to not have to pay for another phone when I'll only use it for medical reasons and once I am financially stable, I can go ahead and pay and probably continue with AT&T. I see your point and understand the predicament I have. I'll just have to wait and see. . .

No problem. I just am trying to see if you'll end up paying to get it unlocked then have at&t block the phone from being used. Good luck.

Unlock Code (to use with diff carrier)

I'll be traveling to Europe for about a month next week and was wondering how to unlock my phone so I can use a prepaid sim card over there.
I know AT&T has an unlock phone website but unfortunately my phone is still under the two year warranty so I'm not eligible.
Are there any tools I can use to carrier unlock for free or any reliable third party services that are reliable and won't break the bank?
Btw, my phone is not rooted. Please let me know what options I have. Thanks!

I have not done it, but I have heard people explaining that they are traveling to Europe just as you are and have gotten the unlock code for that reason.

Yeah, I called at&t and asked them. However, since I'm still under contract they told me I am not eligible until my contract expires...
If I get my phone unlocked via a third party service while I'm still under contact, will my IMEI be blacklisted? I guess I'm just trying to figure out if there will be any negative outcomes from unlocking my phone while still under a contract.

Does sprint unlock their phones now?

I reached out to sprint for the unlock code to unlock my phone. The rep, via chat, told me that my phone is already unlocked to be used locally and internationally. I asked him to give the code anyway just in case, and he said "Unlocking code or MSL code is only for older devices that are not unlock capable."
I thought only Verizon's phones were sold unlocked. Has sprint started doing this as well on new phones?

No its uicc locked domestically if purchased through sprint until paid off, internationally yes its capable of using any sim on non domestic towers.
Once fully paid off etc you can ask for it to have a uicc unlock so it will accept a att sim etc.
I bought it brand new off eBay. Maybe that's why the agent said it is already unlocked?

A friend of mine tried to put a different sim on his Sprint phone outside of the USA and couldn't. He had to call Sprint to unlock it.

Is it a SM-950U or U1 ?
U1 is unbranded version and pre-unlocked. The U is the carrier variant.
The U would have been locked unless purchased full retail and active on a account atleast 50 days per sprint policy.
Sprint technically dosnt have to unlock it if it dosnt meet their guidelines.
https://www.sprint.com/en/legal/unlocking-your-sprint-device.html
Did you try inserting another SIM card in your Note 8 and see if you can place a call?
If it works with a card other than Sprint, it should work even abroad.

"Did you try inserting another SIM card in your Note 8 and see if you can place a call? "
I don't have one to try it. Otherwise, that would have been one of my first tries.
mine got unlocked automatically after ~50 days last fall
i didn't contact them or anything, one day it just ... happened
it was paid in full from Samsung since they had that sweet trade-in deal for Note7 owners

I had to wait 50 days, and it automatically unlocked. No lease, no payments.
Apparently the only way is to call them, If I buy this phone used would I have any chance of unlocking it in the future ?

unlock note 9 AT&T with firmware

hey all
i have one note galaxy SM-N960U
VERSION ONE UI : 2.0
AT&T USA ORIGINAL CARRIER
I need a Flash Rom to unlock it ,to work with my new carrier in Morocco
I think you need at&t to unlock it or pay one of those sketchy places online which I don't recommend.
CAN YOU RECOMMEND A FAST WAY
For me, when I paid off my phone (was on the AT&T payment plan because of a BOGO deal)
I was able to use the ATT website, enter the IMEI and some other bull****, then ATT emailed me the unlock code.
As far as I know, this only unlocked the sim and I switched to Xfinity Mobile.
