[Q] T-Mobile Blocked Phone From Network - One (M7) Q&A, Help & Troubleshooting

Hello,
Some background first. I had my M7 on T-Mobile for a while and got it under their payment plan deal. I lost my job and was unable to pay for the service anymore and I had an outstanding balance on the phone. My account was cancelled and went to collections, which I immediately payed off. The lady said I would be able to use my phone again and all was good...not the case.
I went into T-Mobile and got a new account setup and when they put in the SIM card, I was unable to get registered. They said that since my account went to collections, even though I payed in full and payed off the balance on my phone, my phone is now unusable. I am not sure exactly what they said was blocked (I think the serial number?), but the lady said it was blocked on an inter-carrier system so that it is unusable on any carrier.
My question is, since my phone is rooted and S-Off, can I somehow get it to register on the network? Anyway to basically fake the serial or something?
Thank you in advance!

What happened is that your phone's IMEI number got blacklisted. There basically 2 reasons why your IMEI can get blacklisted:
your phone is reported lost/stolen
unpaid bills
The lady was right when she said that your phone can't be used on any network anymore. All carriers have access to this list and will block phones that are on it.
And I'm also sorry to inform you that changing/altering/faking an IMEI is completely illegal and you shouldn't do it, especially in if you are in the US. And because its illegal we can't help you with this on XDA.
Sorry for these bad news

Try GalaxSim Unlock...http://forum.xda-developers.com/showthread.php?p=30541172
Sent from my SAMSUNG-SGH-I747 using xda premium
I've only ever used Galaxy S Unlock and never had any problems. When my sister took her Captivate to England for a semester, she stopped by the AT&T store and they installed it for her, so that's what they use. play.google.com/store/apps/details?id=com.helroz.galaxysunlock&hl=en
Worst case scenario, you can go to the AT&T website and do the Chat with somebody. Even though they ask you not to do Unlock stuff through chat, that's what I did with my SIII. Twice. They just ask for info on your account and your IMEI, then give you an unlock code.
AT&T won't always unlock phones however. They only do if you meet their criteria, but if you're under contract they won't do it.

Both of my SIIIs were under contract (I renewed in November) and the Captivate was as well. That has nothing to do with it.

What Captivate, i896 or i897? There is no easy way to unlock i896, Galaxy Unlock won't help you. In my case I just purchased the unlock code off eBay.
What you mean by "unlock"? If your SIM card is locked after too many unsuccessful attempts to unlock it, than you need to replace it. No fix for locked SIM card.
old tool
i used a very old method to unlock my Cappy.... it was something related to nv_data.bin file... in the mobile root.. try to search on the forum.. u might find it.. or maybe a new method. :angel:

Not to thread hijack, but when exactly was this? AT&T recently updated their unlocking policies. I've asked several times in the past while under contract and the answer was no. Maybe you just got lucky. My account has been in good standing since I've been with them (over 10 years now), and I never have an unpaid balance. Who knows, maybe I just always get the assholes, pardon my language :angel:

They'll want a good reason, like that you're going in vacation and need to use your phone over there with a pre-paid card under another carrier or something. You might've have to give it a few tries too as not all representatives are fine with that.
There's also a paid app though, Galaxy S Unlock. You pay for the code and they send it to you, once you have it, you put another carrier's sim in your phone, it will prompt ask for the code = done.

The second option is what I've found easiest in the past. I bought the unlock code for my friends G1 a while back, was a few dollars but saved a hell of a lot of time lol.

This was in February. I called in, prepared to say that I would be on a business trip out of the country, but no questions were asked. I said I wanted to unlock my phone, they asked for my phone number and last four, then my IMEI. I waited a few minutes, then they gave me the unlock code. That was it.
That was my second try, though. My first was in January and went exactly as the second but instead of giving me the unlock code, they told me that I had to have been in possession of the device for 90 days and it hadn't been that long. So I waited a month. Given that Captivates are old and that wouldn't have been particularly relevant, I left that out.
FYI, my account has been in "good standing" for 19 years now, and I have never had an unpaid balance. Maybe that makes a difference?
Ah that makes a bit more sense. It could also be that I'm not the primary account holder, so I wonder if that may play a role as well (ie they only allow the primary account holder to ask for unlock codes, etc).

I am also not the primary account holder. I am an add on line to a family plan. All they asked for was the SSN of the primary account holder. When they ask for a phone number, give them the primary account holder's number, since they can't look it up with any other number.
I will also point out that I am the original owner of both phones. Their IMEI numbers are registered to my plan. I have no idea how this works if you purchase the phone secondhand.

[Q] Blacklisted Phone AT&T

Hi guys.
I went through a lot of web sites past couple of months and now I've decided to ask you by myself. I got a present from my GF. Sam Gal S5.
She bought it on a craiglist. She tried it with her AT&T SIM card and it worked. Anyway.. she gave it to me. SIM card denied. I've paid $30 to get a code to unlocked.. Great. Buy what was my surprise. After I got in and made a couple of phone calls to providers I find out that the phone is blacklisted. I tried to get ATT sim card also but doesnt work.
So I started to look for an advice... Ive done root, changed ROM etc. But now... i dont know where else to look.
Obviously it was stolen. But I feel sorry for her and she for me...
Is that just a piece of garbage or is there ANY way to fix it?
I dont even know if im able to ask here.
Any advice or opinions helps.
Thank you
Mike
I think you're kinda screwed...Craigslists scams happen all the time..best bet if your gonna buy a phone on there is to both meet at the AT&T store and go through the whole transfer process.

The official reply from carriers is that once a phone is blacklisted it is impossible to undo. Whether or not it's a limitation of the technology (one-way trip) or if it's just company policy, the output is the same. You and your girlfriend have learned an expensive lesson. You can use it as a wi-fi-only device or a media player, but once a phone is blacklisted it will never be able to connect to a cellular network again.
The reason the phone worked with your girlfriend's SIM card was because the real owner of the phone hadn't called to report the phone stolen yet.

Mike, your situation stinks so bad. I was in a similar spot with a T-Mobile HTC M8, which stopped working after I got it off craigslist and then subsequent IMEI checks shows that it is blocked/blacklisted from T-Mobile's network due to a balance owing from the original purchaser. However, since the phone was not reported stolen, the IMEI is not actually blacklisted/blocked from all carriers, but only T-Mobile. So I bought the SIM unlock code for a few bucks online so that I could unlock the phone for other carrier use. I have tested and verified that my phone works on AT&T, even though it is blocked on T-Mobile. So...you might consider changing your carrier or selling it to someone who can use it on another carrier (with full disclosure to that buyer, of course).

Odd IMEI situation (Nexus 6 AT&T)

So I've been playing with my Nexus 6 (I am the original owner) for a while, and recently PCS'd to South Korea for 3-5 years.
AT&T suspended my wireless service under the Soldiers/Sailors Relief Act, which basically suspends my service for $.01/mo.
Now, AT&T also allows you to unlock your device so that you can use a local SIM in the country you are stationed, however their online support unlock request form does NOT recognize my IMEI???
Is it even remotely possible that flashing other radios/bootloaders/roms can potentially modify the IMEI? If so, how can I go about getting the original IMEI restored? I believe I flashed the Google-Fi rom/radio/bootloader most recently. Should I flash back a stock LMY47E or something like that with radios etc.?
I don't normally ask questions like this, but it has stumped me for the last 4 days and I've done lots of searching with no results. My google-fu sucks apparently.
Thanks in advance.
Nope. Does not change any of the IMEI info. I actually ran into the same thing with AT&T on my old Note 3. The reason it does that is because it ineligible to be unlocked through them. However, cellunlocker.net is great for unlocking phones.
AFAIK, Flashing Radio/Kernel/ROM wont change ur IMEI. I strongly suspect that the issue is on the ATT side not your IMEI.

Holy smokes that was a fast reply!
I actually tried cellunlocker.net first, and they said that they couldn't find that IMEI in their database, and that if I wanted to wait a few additional days they would scrub other databases?
Should I have waited for them to scrub additional databases? I already got my refund back
EDIT: I do find it strange that they wouldn't unlock it or that it's not eligible though. It DOES have their branding. LOL.
There are other sites too. I would have let them scrub other sources.
Depends on how long you have had the phone and if it's financed or still in a 2 year contract.
---------- Post added at 01:25 AM ---------- Previous post was at 01:24 AM ----------
And it's likely ineligible because of the suspended service. Regardless of your military status. I had issues with phone companies doing that when I was in the Army stationed in Germany.
Thanks. I'll give another site a shot and be more patient with it. Hell I haven't been able to use the phone since the beginning of June, I can wait a few more days. HA.
Have seen it before on another thread here. It is ATT being an ass. They will say they can't even find IEMI till the device is payed off. Think other poster had to contact FCC. Hope you can work it out and thanks for what you do for the rest of us.

Actually, the AT&T online tool nearly always returns an "IMEI unrecognized" message for our N6. If you call them, you will have no problem getting a free IMEI code directly from AT&T. Been there, done that....

Again... Been there done that. Had trouble with them. They are complete pricks when it comes to giving out the code. I have always found it easier to either pay for an unlock or use another method. He could try contacting them, but it will take a few days to process the request and in my experience, they need orders to show the duty station and even then may deny the request. I even had one moron tell me no right off the bat. When asked why, he was like "because national security". I laid into that jackass about how stupid he was and how much BS I knew he was feeding me.

You know how it goes. "we say one thing then do the exact opposite" lol
Well its unlocked via the 3rd party service I paid $10 for
For the record, I'm military affiliated as an Army Civilian, but prior service military as well. ATT already has my orders on file as they required them in order to suspend my account for $.01/mo.
At least I have a fully functioning N6 again! Thanks everyone.
Glad to hear. Thanks for your service active or not. :good:

my G4 was reported stolen been using it for more then a year

bought this phone on april of 2016 off craiglist it was unlocked. brother sent it to me to mexico used telcel and then movistar..
and on this past 19th my phone didnt want to make calls only emergency.. i live a place where theres alot of killings as they fight for control of the towns. drug lords are in a battle since feb.. so i heard that when the marines or military are in cities or towns they cut all cell phone comunications. not sure if its true.. so i tought it was that as theres been alot of military on the town and 3 helicopters.. so next day samething but my moms phone was working fine... so i asked my niece for a telcel sim card. i inserted the sim and i got service and called my moms phone.. so i assumed i had a bad sim. but then i tried other movistar sim my mothers and samething happened no service. but not on telcel.. so i tought movistar blocked me. my mom lost her phone a cheap phone and i reported from my phone for stolen.. but its was confusing.. so a might have enter mine.. day after it was locked.. partially as i could use telcel..
so i call movistar and they said that my sim card was inactive cause it was reported lost . i gave my info and customer service activated my sim card again... supposely never tried it in another phone.. then i waited but no service i only get emergency calll only.. so i used telcel for 2 days and then samething it now tells me emergency calls only on telcel too.... called tmobile and they said that the imei was not on their records....tmobile website that checks imeis status and i tried it and it says that it was reported stolen.. after more then a year.??
was it really reported stolen..?? or did movistar locked it.? can they read imei with sim card inserted.? cause ive never gave them my imei.. ??
am very pissed stress anxiuos.. and hurt.:crying::crying:. i hate people that take advantage of others. they deserve to die.. yes die.. we donst need those people... sorry am very frrustrated.. and mad.. i dont like beign lied to.
i happen to have anxiety attacks.. so i gather this money with alot of sacrifice... i cant hold a job besides jobs in mexico are a joke..
I bought a G4 on craigslist and it turned out being blocked. It was blocked because there was an unpaid balance with Tmobile. I bought it very cheap for at the time I got it so i was a little suspicious to begin with but I got it so cheap it was not worth my time and gas money to return it to the guy I bought it from. I got his name and had his phone number and picture i took of him with the phone when i got him to write me a receipt. He gave me some story about he let his room mate put it in his name and and the room mate didn't make the payments and so on. He was willing to give me my money back but i just decided to keep it and use it as a Wifi phone.
I called Tmobile and they couldn't really tell me anything because the account was in someone else's name and they also did not seem to care about getting the phone back and told me they would be glad to sign me up for service and sell me a new phone.
I had planned to use it on Ting and it was blocked...not locked. From what I understand the phone sends out a code ever time it logs onto the network. I am not sure if it is just imei number but there is some unique identifier for every phone. And once the blocked process is done the phone can not connect to the network. I found out companies in the US share these blacklist numbers now and if you are on it there is not much you can do besides changing out the chipset for one with a clean imei. I did not know they were now sharing these numbers with Mexico but it makes sense as i read that a lot of stolen phones go either there or to Europe where the info was not yet being shared.
I really enjoy my G4, even though it is just for wifi use, I use it with google voice. I really hate i can't connect it to a mobile network though, so much in fact that I am considering buying another G4 off ebay or somewhere (an unlocked, unblocked one). If the G4 was waterproof and had a fingerprint reader I would have already bought one. Oh and another thing that is holding me back now is the locked bootloaders. I have been reading and trying to figure out which ones can be unlocked and rooted now. From what i can gather is that 811 and 815 models can still be rooted...and 811s only if they are not updated to a certain point.
Now I am debating Moto G's and a few other phones that are unlocked and will work on all US carriers. I still feel the G4 is a nicer phone for the money than a lot of them, even with all the issues there have been with the G4s. Sorry to hear about your phone, not sure if you have google voice in Mexico but if so you might want to check it out. There may also be some other apps that let you use it as a wifi phone as well.

h811 can be unlcoked but only in MM from version 20i upwards upto latest 20v.
I had planned to use it on Ting and it was blocked...not locked. whats the difference.?
well i have called tmobile and i have heard this morning that its is not blocked from their side.. but last night anotherone said it was.. i had this phone for more then a year.. i hope maybe it isnt blocked by tmobile but from movistar .. as i accidentally placed my sim card number its so confusing.. talked to movistar but they want me to show proof of purchase.. wich i dont have.. at the time i got mine they were around 450$ am really depressed..
Blocked is blacklisted, once it goes on it doesn't come off the blacklist unless the original account owner pays off what is owed, at least in the case of my phone it is like that. Tmobile has an IMEI online checker https://es.t-mobile.com/verifyIMEI.aspx when i enter mine i get a message:
Your device is locked and will not work on the T-Mobile network. If you think this is a mistake, call Customer Service.
Another IMEI checker I use says that: The device has been BLOCKED by T-Mobile carrier.
I guess if i were you and the person at Tmobile told me it wasn't blocked by them, I would have said send me a sim card. And then got their name.
I have read about a lot of people getting scammed with the G4, person finances the phone, sells the phone then files an insurance claim. The person that buys the phone can use it for a while, sometimes months, not sure about years. The process finally catches up, the phone gets blacklisted and the person that bought it second hand and thought things were fine is left with a phone that can't be put on a network. I don't know if that is what happened with your phone or not, just saying it could be. I would check several imei checker websites if I were in your position.
I have other phones but none as nice as my G4, I like the phone and would really like to have it as my main carry phone but now I have seen them for 139 USD new on ebay, a good used one under 100. I may go for one or I may try to get something that is unlocked and works on all US carriers.
I hope you get things worked out with yours. I never even got mine hooked up with a carrier but I have enjoyed rooting it and using it as a wifi home phone and using the IR blaster. I have got moneys worth out of it just doing things like that. I now run Lineage on it and have Hangouts, Google assistant, Atmos and Nova launcher among other things so I am happy. I am pretty sure i don't want one that is not rooted though.
Edit: Locked means it can only be used on a certain network. If a phone is network locked say it is a Tmobile phone, it can only be used on Tmobile.

Blocked is blacklisted, once it goes on it doesn't come off the blacklist unless the original account owner pays off what is owed, at least in the case of my phone it is like that. Tmobile has an IMEI online checker https://es.t-mobile.com/verifyIMEI.aspx when i enter mine i get a message:
Your device is locked and will not work on the T-Mobile network. If you think this is a mistake, call Customer Service.
Another IMEI checker I use says that: The device has been BLOCKED by T-Mobile carrier.
I guess if i were you and the person at Tmobile told me it wasn't blocked by them, I would have said send me a sim card. And then got their name.
I have read about a lot of people getting scammed with the G4, person finances the phone, sells the phone then files an insurance claim. The person that buys the phone can use it for a while, sometimes months, not sure about years. The process finally catches up, the phone gets blacklisted and the person that bought it second hand and thought things were fine is left with a phone that can't be put on a network. I don't know if that is what happened with your phone or not, just saying it could be. I would check several imei checker websites if I were in your position.
I have other phones but none as nice as my G4, I like the phone and would really like to have it as my main carry phone but now I have seen them for 139 USD new on ebay, a good used one under 100. I may go for one or I may try to get something that is unlocked and works on all US carriers.
I hope you get things worked out with yours. I never even got mine hooked up with a carrier but I have enjoyed rooting it and using it as a wifi home phone and using the IR blaster. I have got moneys worth out of it just doing things like that. I now run Lineage on it and have Hangouts, Google assistant, Atmos and Nova launcher among other things so I am happy. I am pretty sure i don't want one that is not rooted though.

Carrier Locked? Sim Locked? UICC Locked? What state is my phone in?

I bought an SM-N960U used off of letgo about a month ago now and I have been trying to get it to work for me but I am still having a few issues.
The guy I bought it from, who himself bought it used, was using it on T-Mobile and I am able to make and receive calls okay and get internet okay with Verizon. The phone was originally a Sprint phone. It continuously gave me "Activation was Unsuccessful" fullscreen messages repeatedly until I used adb to disable com.sec.omadmspr and com.sprint.ms.smf.services.
When swapping SIMS from different carriers the phone DOES NOT ask for an UNLOCK code.
When I first got the phone I tried to call Sprint and ask if the phone was Carrier locked thinking that if there was a small amount owed or something perhaps I could pay it and UN-Carrier Lock the phone... Well, that didn't go well. Since I wasn't on the account and couldn't provide the name or phone number of the old owner they wouldn't tell me if there was OR wasn't a carrier lock on the phone. Eventually I got them to take the IMEI but they still told me nothing.
So, I've been using the phone daily for about a month now, but because of it's problems (the app that won't run) I still have to carry my old phone as well. This phone is always on Roam. One time when trying to fix it I dialed the *228 PRL update number. That was a mistake. It broke my internet to the point where NO ONE was able to fix it. I went to a Verizon stone. No help. I called customer service. No help. They transferred me to Tech Support.... finally they had me swap in one of my older SIM cards and they programmed that one to work.
TLDR; The phone works with VZW voice and data, but is always on roaming, some apps refuse to work properly, under UICC Unlock the phone says it is locked to Sprint Sims and sometimes the data connection drops and it says it doesn't work because of "Data Roaming" being disabled.
What version of locked is my phone? Is it safe to start flashing it?

you probably has nothing to do with your problem but it may be of some help if you contact the guy mentioned in this thread for the LG V20, it's a guy that works for sprint and you can contact him on the Sprint Users forums ..
He may be able to help you with the sim unlocking of your phone, there's nothing to lose I think!
give it a shot ... look at this thread and then register for an account on the Sprint Forums and look for the guy..

You need to contact the person who sold you the device and ask them for assistance. As they may need to contact Sprint to activate the device and unlock it for you.

Thanks, but the guy I bought it from bought it used, so he wont have any Sprint account info, so then I'd have to try to track down the person he bought it from... and on and on and I dont know how long or fruitful the search would be... and again... I'm on the phone right now, on Verizon with a Verizon SIM. I dont think its carrier locked... but then I dont know what's going on.

They don't want to make it easy for people to re-purpose stolen phones. There are things a legitimate owner can do in order to make a phone ready for re-sale, and it sounds like these things didn't happen for the phone you bought. It all sounds a bit fishy, doesn't it?

Thanks, but if I thought "it sounds a bit fishy" I probably wouldn't have bought the used phone in the first place... and I certainly wouldn't have called Sprint and given them the IMEI and asked them; the people that could render my phone a useless brick, with one tiny bit of information, for help. Each smart phone I've bought in the last few years has been used because frankly to me it seems to be the best way to buy them financially. $1000 the day they come out or $200 - $300 6 - 12 months later used.

Point is, when someone is about to buy a used phone from a stranger, make sure it is factory reset and then immediately call the carrier and confirm the IMEI is clean and that it has been carrier unlocked, else, don't buy it. Obviously it's not advice for you, since you already did it the wrong way. This is a good lesson for posterity.
