[Q] Blacklisted SM-G900A -- won't work on T-Mobile, but full service on AT&T

I am pretty confused.
I bought a used AT&T variant S5 from this lady on craigslist. I ask her questions about the phone, try and get a judge of her character, check the IMEI on Swappa, etc. The important parts checked out and the IMEI appears to be clean so I go ahead and purchase the phone. Since I use T-Mobile's prepaid plan, I have the phone unlocked and it works great - for a few days. Suddenly I get the MM # 6 Error and all network connections cease to work.I return to Swappa and check the IMEI and get the dreaded black box telling me the phone has been reported as lost or stolen. Bleh.
I am either victim to insurance fraud or I purchased a stolen phone from this lady BUT that is not why I am posting here. Fast forward a bit and it has been over 24 hours since the phone has been blacklisted and I am still obviously a little pissed off. I tried putting a GiffGaff sim in the phone but it's been ages since I have used that, so I get the SIM Not Provisioned Error. For some reason I thought I would try my wife's sim in the damn thing next just to see, obviously not expecting much better results (She has AT&T). I get full service. Taking the sim out of her iPhone 5S and putting it into my blacklisted AT&T S5 has returned full service to my phone somehow. I disabled Wifi and got full bars 4G LTE, successfully browse the internet, send text and MMS, and make a phone call.
Has anyone ever seen anything like this? I'm sure there is an explanation, but I haven't heard of this yet. I know when a T-Mobile phone is financed and blacklisted, it will still work with AT&T networks, but I haven't ever run into a scenario quite like the one I am having. Maybe there is a slight delay in AT&T having the device updated on it's blacklist vs T-Mobile, where the device is already not working. I did check the IMEI again and it is still blacklisted. Any thoughts?
TL;DR: Blacklisted AT&T S5 works (currently) on AT&T, not T-Mobile

I need someone to say they have seen this before...

It's not blacklisted if it works on Att.

Yet the IMEI shows blacklisted for lost or stolen on T-Mobile? And they share the same database.

I guess my question is why the hell does this phone not work on T-Mobile? Could T-Mobile have mistakenly put this on the blacklist?

Are you 100% sure the phone is natively an AT&T variant and not a Tmobile one? Tmobile variants can flash and at&T rom and have the device ID in settings changed as a result. boot to download mode and check the device ID

Well put it this way: The phone has an AT&T logo on the back, at the boot, and the sticker on the inside says SM-G900A. Also, the phone would bring up the NCK Unlock screen whenever I put in a T-Mobile sim prior to me unlocking it.
After unlock things worked great with T-Mobile, until I got the MM#6 error and check the IMEI again to find it was blacklisted.
Taking a picture now of download mode.

The reason your wife's sim card worked is the imei is not listed on your account. It takes a couple of hours to a couple days for the att network to check the imei and lock the account due to a lost or stolen device (blacklist). Once this happens your account gets locked and unusable until you remove the sim from the device and call att to restore service.

So the although the phone is showing up as blacklisted, it will continue to be usable until AT&T notices its being used by my wife's sim, at which point she will be locked out of her account until she calls to restore service? I have never heard of that.

Just because you may not have heard of it does not make it false. Trust me the info I have shared is the reason why. I have run into this multiple times.

Well its still alive and kicking on AT&Ts network. Your explanation would make more sense if it wasn't.

You are better off reselling it cheap to someone who already knows how to do it and buying a phone not blacklisted. Check ESN before buying

Unfortunately,since it's blacklisted you likely won't be able to get service through any provider, I'm sure there are way around that BUT no one in there proper frame of mind is going to chance telling you how or giving you directions on how to do it (IMHO)
You can't even legally sell the device since that falls under trafficking in stolen property laws in most states, and since you mentioned the "Guy" is no where to be found it's a good bet the device is stolen

Blacklisted means it's on a list that all carriers check when activating. It will usually suspend the person's account within a few mins of putting the sim in. You really do need to check the imei when buying a phone nowadays. It's easy on the swappa site. Changing the imei is a federal crime and not easy to do even if it were legal. Only option I can recommend is trying to get it back to the owner & if you can't, maybe you could at least buy one w/a broken screen and swap em

Get the main board replaced.

Officially sim unlocked using the T-Mobile app!

Posted in a couple threads but thought I should start a new one so that people could give it a try if they wanted...
I can tell you that I have had my S6 for about 4 days and I put my prepaid sim card in it instead of the one it came with (had to create a postpaid account so that I could get this phone!). I tried to unlock with the app on the phone and it told me NO, I am not eligible to do that, but I just tried it a 3rd time about 30 mins ago and BOOM! I am permanently unlocked and can confirm that AT&T works great! The phone rebooted and it automatically froze the unlock app. LOL I un froze the app and sure enough, I am perm unlocked! Not bad for using the phone for less than a week and not calling T-Mobile even once to ask. Just wanted to give people a heads up in case u wanted to try this yourself with a pre-paid sim (if u have a prepaid account, of course). I love my $30 plan! :good:

Damn might have to try this out. Thanks!

omg. att customer here. I want to get a Tmobile phone for a long time (unlocked bootloader)
Can you tell me how did u order it and unlock it more specific?

TMOBILE S6 has an unlocked bootloader - BUT the SIM CARD is locked - the guy who posted here was apparently a long time customer on TMOBILE and because he has had an active account for longer than 40 days, he can unlock his sim card using the ap that comes on the phone. BUT if you want to use tmobile S6 on ATT - y ou may have to wait 40 days to get the SIM Card unlocked - unless you possibly know someone who has been on TMOBILE for a while and they let you use their SIM Card to get your phone unlocked....

so just put friends tmobile sim in there, and launch that app right after? or..... u are saying I HAVE TO let my friend play with my NEW S6 for few days. then use that app to unlock it.
Any other way I can get unlocked tmobile devices? I think last time I saw staples.com was selling unlocked tmobile lg g3.

I am not the one who discovered this - but from my understanding - you should be able to put the TMOBILE Sim Card into the phone (from the friend who has been on TMOBILE for a long time) and from what someone else said, the unlock ap wil unlock hyour phone. Then switch the Sim Card with the ATT sim card and you should be good to go.
Check oout the QA Thread for details - here is the post where someone else explained it: http://forum.xda-developers.com/tmobile-galaxy-s6/help/unlocked-s6-att-t3069140/page2 GOOD LUCK -i hope it works for you - I don't know anyone on TMOBILE so I can't try it myself yet...

There seems to be some misinformation in this thread. I am a prepaid customer who hops around from different prepaid companies for the best rate plan/price and am currently with Harbor Mobile (T-Mobile agent) and I purchased some minutes for my prepaid $30 plan on T-Mobile prior to grabbing the S6 JUST so i could test out the unlocking. The unlock rules apply to each device that are on your account so while I may have been on T-Mobile prepaid for about a year, it was off and on and NOT continuous service which you must have at least 40 days of continuous service PER device that u want to unlock. So, I unlocked my Note 4 a couple of months ago through them but I just received my S6 so I would have had to wait 40 days to get my unlock because it's a new device AND I have failed to maintain continuous service for 40 days anyways, even if the other rule applied. Also, the reason I mentioned that it worked on the 3rd or 4th day I had the phone is because it literally takes T-Mobiles system that damn long for them to actually tell which device you have on their network. I don't know why they can't tell right away but I have swapped devices many times and I have found out that the 3 day rule applies ( at least to prepaid) cause when I call them up for a question or problem after I have swapped my phone they have no idea which one I'm using so anyway, I just wanted to give some more insight on what I have experienced through my time with T-Mobile prepaid and how their system works based on what I have been told and my experiences. I can almost guarantee you aren't just going to be able to throw your buddies sim in and unlock your phone! That would just be waaaay too easy and why would any carrier want to give you the easy way out?? LOL Anyways, take care guys and hopefully I helped answer a few questions. I will be off and on so I can answer any questions u may have relating to my experiences. You most certainly can try any method you think may work but I think I got lucky somehow and really it was VERY odd! I think it will be figured out very soon though so no need to worry as we already know they can be unlocked and I already confirmed this model works with AT&T 100%. :good:

Used my friend's Tmobile SIM card, and tried permanently unlocking it, didn't work. Even Temporary unlock didn't work. He's been a long time customer with TMo

I can confirm that official T-Mobile "Device Unlock" app unlocked my phone. First thing I did when I got the phone.. Using the T-Mobile Sim that came with the phone, opened up Device Unlock (pre-installed by the way), confirmed to unlock, no freezing no nothing it just worked and rebooted.
Phone is on a business account, upgraded via Jump 1.0, unlock prior to the OTA if any of this matters

It sure does. Business accounts can be unlocked much quicker than personal accounts. Lucky you, enjoy her--she's a beast

i paid in full for the s6 , when i tried to unlock with the app it said cannot be unlocked , contacted the cust. support and they said you have to wait 40 days
i went to twitter and wrote some tweets to @Tmobile usa and they responded immediately and after showing them the proof of my purchase they said to try the app again and it worked ,,,
twitter helps

Just to be clear...
Everyone who successfully attempted this paid off the phone in full?
No EIP? Correct?

Just here to check updates. I am a full on tmo customer and am thinking of trying this. Even though I don't need it. Would be nice to just have it.

Making an ATT Note 9 (unlocked) work on Verizon Wireless

Hi Guys,
I purchased a used Galaxy Note 9 that has the ATT startup and boot animation. I check the IMEI number and it's good, so I went ahead and unlocked the phone through a paid service. When I insert my Verizon sim card, it says that a "Network Locked" sim card has been inserted.
Do I need to load a different firmware to get this to work? I thought the Note 9 supported both GSM and CDMA with the same hardware, but maybe I'm wrong. I haven't posted in here in a while and if this is in the wrong spot, I apologize.
Thanks in advance!

Thanks man, just signed up for his service...I will let you know how it pans out. Thank again!

So I was able to get a Note 9 phone I purchased used sim / network unlocked. It was previously on ATT and I'd like to use it on Verizon now. Is it possible to do this? It shows my number, but any other sim information says unknown.
I'm guessing I have to load some kind of Verizon tower info (terminology might be wrong). I thought that stuff is in a CSC file or something. Not sure if I need to flash a whole new ROM, but any guidance would be appreciated.

Once you unlock the phone it will work with Verizon and will configure all the settings as soon as you insert the aim

That's what I thought, but this isn't working. It keeps bringing up the ATT boot animation. I did confirm again that the IMEI is successfully unlocked, but when I login to Verizonwireless on my PC and enter the IMEI it says it's not compatible with Verizon's network.
Is there a database somewhere that has this as a GSM only Note 9. This phone came from an ATT customer...who got the buy one get one free. I sim unlocked it with a third party service.
I'm just wondering if I'm under the false pretense it can handle both GSM and CDMA networks and maybe I'm locked to GSM only...
Any advice is greatly appreciated!

You need to flash it to Verizon firmware . Unlike the note 8 carrier versions , the note 9 doesn't rebrand to what sim card is installed currently.

Hi I successfully flashed Verizon firmware and it still doesn't work.it still has att splash screen and won't connect to Verizon. Please help

Just to make sure that the phone is actually unlocked try T-mobile Sim see if it works.
And if T-mobile sim works then Try N960U1 (XAA) Firmware which is USA unlocked firmware for Unlocked Samsung Note 9 that works with all carriers. so once you insert Verizon sim, it should reboot and set it up for Verizon network.
I did it with T-Mobile Note 8 and was able to use it on Verizon network. Right now I have a Factory unlocked note 9. N960U1 can't really test it because it works with all carriers out of the box.

Did you ever got your AT&T note 9 working on verizon?

I haven't had access to any active Verizon sim cards so I could test them. I just got my note 9 512gbyesterday so I'm gonna give it a go. I'm sure it can happen. Where there's a will there's a way. My only issue is paying 53$ for unlocking. I know there are way cheaper services, I just want to be sure its credible

I have an ATT note 9 unlocked the sim, installed Stock SM-N960U1 USA Unlocked Firmware Odin "N960U1UEU1ARH2" and everything is working like a charm with my Verizon sim card.

How do you find this software?

I'm not w/VZW,but,I believe if your VZW SIM was activated in another phone,you should be able to drop the SIM Card in (& possibly setting up the APN) & that's it.
However,if you're starting new service w/VZW & the SIM Card hasn't been activated in another phone yet,a call to VZW's customer care is likely in order to get things rollin'.
Again,I'm not w/VZW,just going off memory of what I've read around various sites,so,if your still having issues,contact VZW.
FWIW,it's not the hardware,all US Note 9's are identical on the inside (less storage & RAM options).
Also,some have wrongly stated that flashing firmware will somehow magically SIM Unlock a phone,this is the furthest thing from the truth.

I already had the phone unlocked through a service. I got the code put it in and it said unlock successful. But when you start it up Att logo still shows up and the Verizon Sim does nothing. Other forums say you must upload the unlocked software from the unlocked version of the phone??

There's a few things that could be going on:
1) Even though you checked the IMEI to be clear,that is not a 100% full-proof guarantee of anything,less some proof the phone was paid off in full before you bought it.
Also,the phone might have been reported lost or stolen after you purchased it,but,before you actually took delivery of it (A scam artist coulda sold you the phone).
2) Not knowing which exact unlocking service you purchased,whatever you paid for may not have been what you needed for an actual SIM Unlock.
3) If the phone indeed was/is originally an AT&T Model,I'd guess you'd need to be running that firmware to ensure a proper SIM Unlock,but,don't quote me on that,for now.
I'm guessing you're gonna need to contact AT&T customer care regarding the SIM Status of your phone.................
Once that's resolved/SIM Unlocked,if you want to move to VZW firmware,yes,flash the unlocked (SM-N960U1) firmware 1st,then the VZW firmware afterwards,to ensure full functionality for VVM/Wi-Fi Calling/etc.......
You might be able to somehow get all of that working on unlocked firmware,but,I'm not up on all-things-VZW & the Note 9.
But,1st things 1st,get w/AT&T & see if there's anything going on preventing the phone from being SIM Unlocked before you waste any more money on SIM Unlocking services.
As far as paid services,I've used Masterunlockcode & UnlockBase w/a 100% success rate,there's others out there,some mentioned in this very section/thread..............

N960U / U1 Carrier Switch & CSC features not working? Help?

Ok so on my N950U I was able to flash the N950U1 firmware with the N950U (TMB) CSC.
This would give me U1 firmware with carrier icons and carrier features. It worked great.
I tried that on my new N960U. It did indeed work with the exception of one thing.
The RCS messaging (read receipts / typing etc) stopped working. Can anyone here shed some light on to this or have any idea what has changed?
Thanks!

Are you confusing this with the carrier rebranding function of the note 8 ? The note 9 can't do this currently.

Multiple threads about this already. Or just search for my posts

I followed it and it still shows sprint as brand in settings, did i do anything wrong here?

I know it's been a while.
Any idea if/when Samsung will enable this?

I'm on PIE and when I put my sprint sim into my unlocked T-Mobile phone it went to sprint towers and got sprint Bloatware etc.
Problem is sprint does not know that and they will not activate it.
Any way to get it activated on sprint?

Not unless you can sweet talk Sprint customer service to whitelist it. Sprint will only activate factory unlocked and Sprint branded Samsung devices.

Interestingly I just called a corporate store they said that the device is coming up as internationally unlocked but not domestic so I would need to get it domestic unlocked in order for it to work.

Sorry I can't help you. I have zero experience with Sprint myself.

Are you the original owner?
If so,did you use the T-Mobile Device Unlock app & ensure that it is indeed permanently unlocked vs a temporary unlock?
If you are not the original owner &/or the device still has an outstanding balance,this may be messing things up for you.
Repeating myself here,but,just in case you've read somewhere that changing the firmware somehow SIM Unlocks the phone,it does no such thing.
As for the hardware,there's no reason the phone shouldn't work on Sprint,less their pointless/consumer hostile practices of their brand of BYOD.
No carrier is perfect,far from it,but at least w/T-Mobile & I'm guessing AT&T,no hoop-jumping is needed,simply dropping in a SIM Card (& possible APN adjustment) is it,no further action necessary.
Whatever the person told you (from Sprint) seems to contradict what is posted on their website.
Give these two links a shot & see if you make any headway:

I am the original owner bought it in full from Samsung. T-Mobile unlocked it when I bought it.
I used the t mobile device unlock app to unlock it once they said it was unlocked and used the Permanent unlock which than removed the app automatically...
Will check out those links.
THank you

Cool,please keep us posted on your results. :good:

Your probably out of luck. Sprint activates there phone differently then any other carrier. All other carriers, pop sim in, and it just works. With sprint you pop sim in and nothing. Have to call and give info, but they won't activate it.

got 2 sprint reps (one on the sprint community forums and one phone rep) to submit a ticket to have my IMEI added.
let's hope they are successful.

You using the correct sim card type for the note 9 on sprint?

I don't think that's the problem.
The problem is that sprint needs to activate the phones imei and they are saying that thr imei is not eligible.

What sim card type are you using and yes believe me it matters.

The correct sim card type is needed to make the Note 9 work on Sprint. SIMOLW506TQ or SIMGLW406TQ. Once you get the correct sim card type then do an Imei swap via online chat. Dont bother calling them up.
