How is AT&T Detecting my phone?

How is AT&T Detecting my phone?
In my online account management you can select your phone type. Currently I have "AT&T 8525" selected (which is my phone of course). When I go to select "My Device is not listed" or something else, it will remain selected for a while, then when I log in sometime later, "AT&T 8525" is selected again.
How is AT&T figuring my phone type out? What kind of information about my phone is being automatically sent out? Is there a way to block this, or even spoof it?
Is it possible that at&t is just guessing?
I'm using WM6 w/ HardSPL loaded.

I wouldn't sweat it dude, I've had mt 8525 since June and AT&T still has my phone listed as a V3 Razor but, they have my kids phones listed right. OH, I havn't had a razor for almost 2 years.

Same. I've had about 3-4 phones since the Razr, mine still says razr

Yeah, it took AT&T three or four months to update mine when I first got the 8525. Once it even had me listed as using one of those old Nokia bricks for like two weeks, then went back to the 8525! Wierd.
Anyway, I could be wrong, but I believe your IMEI is what tells AT&T what kind of phone your using. It just seems to take AT&T's system a while to play catch up when you switch phones.
...and changing/altering your IMEI is a dangerous topic on this board, as it is an illegal practice in most countries.
Anynody else know of how they detect your phone model?

they have spies......watching you, all the time.......
the IMEI is right. that's how they do it. and the spies help sometimes too

Yes at&t can tell what IMEI is what phone. For that matter most everyone can find it, if you have the IMEI, on the Net if you look hard enough. If you go into a store and register your V3 IMEI on the account the phone should change in the Online managment page. But with the implimentation of their newest system, D.E.R(Device Eligibility Restrictions), they can tell what IMEI is being used with what phone number, even though it may not reflect on the "Online Managment" Site. More importanly, D.E.R restricts certian packages to be allowed for what IMEI is registered on the account.
For example if you have a V3's IMEI registered on your account, then the Media Net package for 15$ unlimited usage will show up and the PDA Connect for 30$ will not. This works in the oposite manor as well. This makes it harder for us to use the lower priced packages. Eventually if D.E.R catches the fact that you are using a PDA phone with the 15$ package or any of the other "Non-PDA" Packages, It may take some time, but the package WILL fall off and credits will not be given out, or atleast that is what i have come to understand.
Hope that clears it all up. I do work for at&t Mobility, im at the bottom of the totem poll (Agent), but one of my larger business accounts has already run into issues with D.E.R and credits were not given out.

I knew it! ...and my suspicions about the spies have been comfirmed... ^.-

Fun With AT&T

Some strange events happened to me yesterday. I've had my g1 since december of 2008. I bought it off someone at craigslist because I am on a AT&T family plan and didn't want to switch carriers. I unlocked the phone soon after and have been using my phone happily since then. I also do no have a data plan and make sure to remove all APN information after each flash.
I have been happily flashing roms going from 1.1 to 1.5 and to 1.6. Lately I was using "NonSense Cupcake revolution" but yesterday I decided to update to cyanogen 5. Right after the upgrade, I got a text from AT&T congratulating me on my new smartphone and telling me that I now need a data plan. 10 minutes later we found out that AT&T deactivated all our sim cards and none of my family were able to make phone calls.
Does anyone have any idea what the heck happened? How did AT&T know all of a sudden I was using a smartphone. Is there something about android 2.1 that raises a red flag? I really DO NOT want a data plan and will rather stop using my g1 than pay $350+/year on one. My current plan is to give them my old Nokia IMEI when I get my new SIM card and then pop it into my g1 after downgrading back to the 1.5 rom I was using.
Thanks for reading and I look forward to hearing your ideas.
Edit: New theory; found this elsewhere:
"Note: If an AT&T customer puts their SIM card into a Nexus One device, our smartphone data requirement policy and control rules will apply; this allows customers to enjoy the benefit of using data services from AT&T. The following welcome message will be delivered:
Your Smartphone is active! A data plan is required and if omitted, will be added to your account. For details, see your sales rep or att.com/smartphoneplans."
So AT&T thinks I put my sim in a nexus one so I think if I downgrade I should be fine. Any way to make a 2.1 rom look like a 1.6 one? build.prop maybe? I cant test anything myself until I get my new sim.

Call them and tell them you put your sim card in a borrowed phone lol. Push a build.prop from any 1.6 to change your id. For fun, open the build.prop with notepad and change g1 to Nokia 1100. If you don't use data they can't charge you

Ha we think alike; I told them exactly that yesterday. What value of the build.prop would I need to change to make it look like a nokia?

There you go=p I just changed every time it said dream, htc, or passion and changed it to nokia=p I don't think that market will work right though. You could try pushing the build.prop from a 1.6 build to cm5 but then i don't think video would work, so you will probably need to merge the 1.6 build.prop with the 2.1 build.prop.
Rename to build.prop and push to /system/

Thanks dude. I'll be sure to report back on Tuesday or Wednesday and tell you guys what happened.

Odd. I never had this issue.
I've been using my G1 with AT&T for some time now.
The update to 2.1 (CyanogenMod) didn't result in any variation for me.
Of course, I am using AT&T's "dumb-phone" unlimited internet... even still, there appears to be no indication on their side that I have a smart phone let alone a Nexus One.

Same with me. I am also using the $15 dumb phone data plan and a switch to CM5 did not trigger any notification from AT&T's side.

Quick update: I wussed out and flashed the backup I made of the 1.5 rom I was using. I didn't feel like risking getting "caught" again. I got to play with cyanogen's new rom for a few days and while great it did not drastically give me anything I didn't have before. I ended up giving them an old nokia imei as my phone and putting the new sim in my g1 shortly after. No texts forcing me to get a smartphone plan yet. I doubt I'm the only one that will have this problem so I'll just give a warning:
If you have AT&T with a g1 without any kind of data plan, after updating to android 2.1 they might try to force one on you.
Thanks for the help and ideas. I'll post again if they try to get me to get a plan again.

If AT&T actually offered 3G coverage in my area (a major city, imo) I might consider it. Otherwise, they can polish my knob.

This doesn't have anything to do with the version of android you are running. They can't detect that. They CAN detect your IMEI and compare it to the database to determine if it is a smartphone or not.
Alternatively, the thing tried to connect to a data service when you plugged your card into it, and they looked at the data and determined that it was consistent with a smartphone, i.e., dumbphones don't try to connect to google on port 5228.
Very likely the reason this happened so suddenly is one of the two things;
1) it corresponds to the end of their infinite data plans.
2) it corresponds to you "activating" your google account on your phone.

Interesting. I'm not sure about the IMEI thing since it is a t-mobile phone runnning on an AT&T network. I just find it too much of a coincidence that the problem occured right after updating so I doubt its that. They also haven't reported anything since putting my new sim in my phone 2 days ago.
I guess you're right about them not knowing what version of android I'm running but there must be something in 2.1 that raised a red flag. I deleted an APN file from /system/ before I even booted the rom for the first time so I don't even think its possible that it tried to connect to them. Strange stuff.

You don't think that ATT can read the IMEI from a phone sold by tmobile? I can guarantee that they can. Or if you're worried about ATT being able to link up an IMEI to a type of phone... they can link the IMEI to a lot more than that.... I'm not sure if you realize this, but the IMEI exists ***FOR A REASON*** and it isn't just to look pretty....

The Type Allocation Code (TAC) is a portion of the 15-digit IMEI code used to uniquely identify wireless devices.
The Type Allocation Code is an 8-digit number that identifies a particular model (and often revision) of wireless telephone for use on a GSM, UMTS, or other IMEI-supporting wireless network.

The coincidence is that you happen to be updating your phone when ATT happened to be changing their policies.

That's because they probably do it cyclically, or they put your account into a freeze period after a manual adjustment.
It may ALSO have related to rebooting the device -- connecting to their network that first time after they initiated a policy change may have triggered a routine.

Nope. Nothing special in 2.1. In fact, it would be quite a security violation if it were to broadcast itself out to them.

So I guess it's only a matter of time before they detect my g1. Pitty since I was using my phone for over a year before all this happened. It's weird that they make you read out your IMEI to them while activating a sim card as if they can't see it. I'm just going to keep using my phone as is for as long as I can. The vibration on it no longer functions so I won't be supper crushed if I have to change phones to avoid a data plan.
I have 3-4 friends who have t-mobile branded blackberrys and android phones without a data plan on AT&T. Our school has wifi everywhere so it is truly unneeded. I guess their "check" cycle is fairly slow as none of them have had problems yet. Maybe the process isn't automated yet.
I really do appreciate the information although it's not exactly what I wanted to hear.

This isn't terrible. I can always do this but there's no rush I guess.
edit 2: Is it possible that an attempted apn connection (data) is what caused the detection? I said I deleted a file but looking back on it, it may not have been the correct one to prevent connections.

It is possible.
Note that the rep you read the IMEI out to may NOT have had a read-out of the device model ID. In fact, doing that might freak some people out -- you know, the whole big brother knows too much thing.

Finally some resolution. Turns out a woman stole my mom's identity and went to a wal-mart and bought 5 blackberries under our AT&T account (probably to sell on the black market). Our SIMs where soon deactivated like I said in the OP and the smart phone text had to do with those phones rather than my phone. Upgrading to android 2.1 had NOTHING to do with it (of course). It was all just a coincidence. The strange thing is that AT&T never told us about these new numbers, even when we were reactivating our new SIMs, and we found out when checking our monthly bill.
Now we have to go to the wal-mart where the people committed fraud and try to find out who did it and file a police report. We might end up being charged $400 in deactivation fees. Well that's how it all went down. Funny. I upgraded to android 2.1 at 4:30 on that day and booted my phone at the EXACT moment they bought the fraud blackberries. Ugh. I know this is largely unrelated to android or my g1 but I thought I would let you guys know in case you were curious.

Sorry to hear about that. Your mom might have to pay the fees but as long as the individual(s) in question are found, you can always take civil action.
Surprised no one brought this up but, ATT and all the other services can't turn your service off just because you're using a smartphone and don't have a data plan. That is an optional addition to your monthly bill and as long as you are not using data, they can't charge you or force you to buy the data.
If you're dumb enough to sign a two year contract that requires a data charge monthly for the duration of the contract..well, yeah.

If the phones were added by someone other than the account owner, the service provider has no legal grounds to hold you accountable for it. Fact is that this was a failure in THEIR security and/or walmart's. The service provider should have some procedure to make sure that the person adding the phones is actually who they claim to be.
If not, then you sue ATT AND WALMART for this.

The Ntelos S5

I have an ntelos S5 (G900R7). There is no development for this phone anywhere on the internet. Perhaps I can find support here?
---------
So far (you may skip this part):
I have managed to successfully install Spirit Rom with full functionality, by copying my old build.prop into the system directory, and restoring my previous apn settings using the apnsbu. I forget why I left this rom, but I did. Everything I try has some problem! I then proceeded to try just CM11, by itself, and had 3g difficulties. Then, using Kushman's sprint MIUI, (Ntelos shares sprint towers) things seemed to work right, but it remapped my recent app key to menu... (perhaps I can map it back?) and the volume was not controlled by my physical volume buttons.
-----------
Now my favorite rom so far: Mokee Rom It's fast and visually pleasing, but I have wi-fi and phone difficulties.
After imposing my APN settings, I can reproduce these effects:
(1) Before replacing build.prop, the wi-fi works and can be enabled or disabled as I need. Also, 3g works very well at nice speeds, but it says "Verizon Wireless" underneath the 3g indicator bars. However, I cannot make calls. If I attempt to do so, the 3g data stops working, turns orange, and no longer says "3g". If I do this, then no data can be transmitted or received.
(2) After Replacing build.prop with the "good original" copy (which sometimes fixes similar problems in other custom roms) the wi-fi becomes stuck in a constant state of "turning wi-fi on..." but never turns on. 3g still works, but, as in part (1), it will break if I try to make a call.'' Also, in this case it says "Sprint" instead of "Verizon Wireless"
Does any one have advice, or perhaps some build.prop settings to modify? Or maybe there's a different file that would help. Again, my phone is the SM G900R7. Has someone else with this phone had luck customizing it?
Thank you

nTelos S5
Likewise have a nTelos S5, have not found any custom roms that can successfully be installed without data or phone issues.
Also trying to install any ASOP roms resulted with all phone efs data getting cleared.
Upon searched relentlessly the only rom I found that functions is located at
http://teamcspire.com/index.php?/topic/112-gs5-g900r7-r2-teamcspire-nd8stock-deodexed-101814/
its very stock but functions flawlessly for me.
Advise if you have any luck, I will reciprocate.

My advice is to you, is that if you install Mokee rom, do not update it with OTA update. This is what I think broke the network for me. Even after restoring my phone to factory conditions and using Kies, I still had no network. I ended up going to the nTelos store, where they had to reset the network service for my phone on their end... strange.
Anyway, I have made a few roms work, and I suspect I could make more. If you maintain your apn settings, and build.prop, you should be able to make Spirit rom work. The same thing is true for Miui. However, if I remember from my experience correctly, if you do install Miui, then I THINK you should not restore your original build.prop; it may work without it... just restore the apn settings. When you do this, you may have to change the preferred network mode... I am a little freaked out, after my previous experience with Mokee rom, to mess with this any longer, though. I do have a problem with Spirit rom: if I use the Timely alarm clock, the time panel is miscolored, but I believe that could possibly? be fixed by flashing a different kernel. I plan on flashing Spirit tonight.... stock uses up my battery too fast, and Spirit just feels more responsive.
EDIT: I just re-flashed Spirit Rom, and they fixed the discoloration in the most recent version! Also, as before, my 3g and WiFi work fine.

Took me days...
The CSpire shares the model number and ROM. The US Cellular CM11 is the closest. Somewhere in that I lost my ability to send texts (not sure if it's the SMSC or...) and didn't get it back when I ODIN'd to stock. I would LOVE to have CM support for this model.

I also am in the same boat as you guys. I would love to get another reliable ROM on this phone. I just have bad memories of purchasing my last one (Sprint GS3) from ebay, and having one hell of a time making the MMS work after flashing it for nTelos. However, I never did have to mess with any of the APNs or build.prop settings on that one. I would think the Sprint ROMs should be the closest compatible ROM, being that nTelos and Sprint do share towers in WVa and Va (Sprint actually has zero towers in these states, and leases nTelos towers instead).
Is using EFS Backup by Wanam a good method to insure the EFS does not get screwed up?

You might try saving out your wpa_supplicant file from the stock ROM and replacing it on the flashed ROM. This has worked for me before on my GS3. That might take care of the wifi anyway.

I'm also on ntelos with the s5 now. But it is a us cellular unlocked by them phone. Stuck in a ntelos sim card that I bought from store and everything works. Except 4g. I can live w/o it but it's kinda like a puzzle now. How could I enable this to work on ntelos?

Depending on where you are, ntelos does not have 4G in many places yet. It's still very spotty in West Virginia.

Has anyone taken the OTA Lollipop update? If so, how is it working and does it lock or put in a new bootloader?

I have. It's a little laggy at times, gets really hot when using it while charging and battery drains a little faster. Not sure about the bootloader

I think I will hold off for a while. My stock NK1 is laggy enough as is. Damn, I wish there was a compatible ASOP ROM available for this phone.
Honestly, this Samsung G5 is the absolute worst phone I have ever owned! I would like to get a S6, but my experience has been so bad with this S5, I am almost afraid to stick with Samsung. However, my S3 was awesome!

Just found out that the heart rate sensor is active when the phone is on no matter if S Health is open or not.

I am in the Richmond area on Ntelos. They have stated they have sold their bandwidth to T-Mobile and we are to find another carrier. My phone is not even a year old and no other carrier will activate it. Being I own mine outright and paid close to $600, I am about to lose my mind knowing that I will have a shiny expensive very small tablet in a few months. Has anyone a clue how to change this phone over to GSM or something useful. Verizon refused to even try, though I know when I tried Straight Talk's Verizon Sim it did dial to Verizon's customer service. But Straight Talk nor Verizon would activate it.
Ideas and suggestions welcome.

page plus,i am an ntelos dealer and pageplus dealer i flash phones to and from both companies everyday i am in ruckersville va 12 mile north of charlottesville lemme know if you need help you right its the enitre eastern side of the companyh is gone now to tmobile but you can still activate on frawg..ive done many for customers

Thanks for the info. I am on the frawg side of things now. Their plans were too much when mine ended and I didn't need a phone at the time. Then a few years later, yeah I made my S1 last almost 4 years, I bought the S5 late last year outright. Loved the S1. Made that do everything it just did everything slow at the end.
Anyway, am glad there are options of some sort. Have been reading the reviews of pageplus. What kind of speeds are you getting on it with 4G? Their map shows coverage everywhere which makes me a bit uneasy, as in too good to be true. Is it a simple flash or require editing?
If I can't do something else with the phone, I may try the band opening options. According to the phone specs, it should already have all the Verizon bands but they refuse to activate it due to the meid it seems. I have a feeling this topic may get more viewers as the Ntelos off switch day comes closer.

Google Fit was the culprit for the heart rate sensor staying on. Un-installed it and fixed it

After all this time, has anybody found a ROM that works well on this phone?

can't get data so Internet not working on galaxy s5 unlocked already switched ntelos

You might want to contact your cell phone company and let them know you switched phones. They might need to do something on their end so the sim will work with your new phone.

Thanks for the suggestion but when I swap my SIM into any other phone I have it works fine and picks up a signal without an issue.
Anyone else have any other suggestions that I can try. Got the phone for a good price and I was hoping to resolve this signal issue.
I even tried flashing custom Roms, and vendor and radio's nothing seems to work. I've ensured my APN settings are correct as well.
I hoping it's not hardware (antenna).
I don't know what else to try.

I actually just looked up the warranty status on the 6p and found that it's in warranty until August! Looks like if it turns out to be a hardware issue I'll be sending it to Huawei

Just read the fine print and it states the warranty is only valid for the original purchaser with a proof of purchase

I was having a similar issue yesterday too. H1511 from VZW to Tmobile. No data but could receive calls. I ended up installing one of the custom roms (Pure Nexus or Resurrection Remix, both worked for me ) along with a vendor update (N4F26J_vendor.img) and am now getting signal/data.

Thanks I did flash a custom ROM and vendor update to test but it was a different vendor. I flashed Chroma ROM and I believe the vendor file was MCT40 (something close to that). I'm not home right now to check but maybe I'll try flashing one of the Roms that worked for you along with the same Vendor file.
I'll let you know how it goes.

Cool! Good luck to you. Not sure if you have tired yet, but you might just trying getting VZW to switch out your sim.
------------------------------------------------------------------------------------------------------------------------------------------------------
I have been using the Resurrection Remix rom for the past day or so.
Pros:It is nice, lots of customization. Cons: Some settings will not stick or have bugs. Voice unlock being the primary one. Another setting (vibration related?) was actually located in two places.
I used Pure Nexus for about a hour and thought, well I wanna see what Resurrection Remix has to offer and jumped ship.
Pure Nexus, as the name implies, seems a lot cleaner the boot animation is pretty close to the stock one. And everything I tired, just worked.
*YMWV as review period was short and this model is a second hand unit. Additionally, I am not an expert!

Thanks but I don't have Verizon. I use straight talk with an AT&T sim.
The newer radio/vendor images didn't work for me, flashed a new ROM as well. Still no go. The menu looks different but it still won't give me a signal or turn the cellular radio on.
It recognizes my SIM and tells me I have voicemails but still can't make or receive calls, no mobile data, etc... Popped the sim back in my 5x and it works fine.
Not sure what to do at this point.
Might just set the phone back up to stock and sell on eBay as is. I wish I could've gotten it to work though.

Sorry, I mistook.
Have tired to see if AT&T and will trade out your sim card?

All good.
It's not the SIM, SIM works fine in any other phone. I have 4 other phones I've tested it in.
If I was to try and switch it out I would have to buy a new SIM from Straight Talk.

Note 4 no longer supported by T-Mobile No Network

My husband and I both have a stock N910T. When we woke up yesterday neither phone would get signal, and not even make wifi call. Went to TMo shop today they told me that they were no longer sending signal to Note 4's (Thanks for the heads up TMo). We really like these phones and I wonder if I could root them and flash a stable ROM and get service on them again. When I pull the sim it shows 5 bars, put the sim back and X. I have rooted many phones, but not since I got this one 6 years ago, so I'm sure I'm a bit rusty.
Any advice highly appreciated. TIA

I'm in the same boat with the note edge. It stopped working friday night for me. Put the sim in a stock note 4 and same thing, so I thought my sim card died. Went to the tmobile store on saturday and they said 2 people had came in with the same issue and they had note 4s.
What I don't understand is how they can just stop supporting a phone. I thought that if it accepts the sim card and has the proper bands it'll work. I mean for ****s sake my car takes a tmobile sim for a hotspot and traffic updates.

same exact. i just factory reset and updated stock to see if it would fix but it wont. Any solutions here??

Try to:
a. flash a custom TWRP (recovery) with Odin
IMPORTANT - after you flash TWRP PLEASE TAKE A FULL BACK-UP!
b. flash a custom ROM with root
c. why root? because you can change the build.prop file and "pretend" to be another phone (newer more likely) so that the lovely t-mobile can still allow your phone to connect to the network.
This way you have zero costs, you keep your note 4.
Unless it's too complicated or the procrastination level is TDH (too damn high)
Or you have the cash and buy something new(er).
There's info on this forum about all these steps.
Before you do anything - go and read, search on this forums and on youtube. There are a LOT of tutorials.
Please be careful and READ. Get educated about custom recovery/ROM's.
You will get good knowledge and your satisfaction on make things work will be enormous.
You will be responsible on your actions with the phone.
Good luck.

mine is already rooted with a custom rom. which parameters do you recommend changing in build.prop?
my audi is older than the note 4 and data works fine and calls work on a motorola L6 from 2005, so I doubt it's the age.

someone on reddit came up with a temporary solution until they fix this. you'll lose 4g/LTE tho
To set to 3G/2G turn on airplane mode and enter *#2263#* on the phone dialer. Then select GSM/WCDMA Auto. After that turn airplane mode off.

Hey all - same issue here - Note 4 stopped working Friday morning. I tried everything on my end (factory reset, ROM flash, SIM swap, etc). I even tore the phone down and checked the connections. I ordered a replacement SIM / SD card tray reader thinking that was the issue. Now I hear others having the same issue. I live in Colorado FWIW. Calling into T-Mobile now to see if I can get some info here.
---------- Post added at 02:50 PM ---------- Previous post was at 02:31 PM ----------
After speaking on the phone with a tech support person, T-Mobile reported that they were aware of an issue with Note 4 users not being able to access the network. They said that they "were in contact with Samsung and were actively working on an issue" and reassured me that they would have a solution for customers soon. I sure hope so because I do not want to give up my Note 4!

Note 4 user here too. This sucks. I did the workaround on the dialer posted in one of the above posts, and now it connects. Says 4G at the top, but probably only 3G. That's fine for me in the meantime, but not acceptable in the long run. I just spent 2 days wiping the phone, unrooting, etc only to find this now! Got lots of work to do to get it back to my rooted state. Thankfully I have the backups to do it, just have to find the time now. Thanks T-Mobile!!

Has anyone heard any more on this issue?

Just had the same issue. Called T-mobile support and they had no idea of a widespread issue, said it was likely HW failure. I got a new SIM and that didn't help. Called local cellphone repair shop and they indicated they'd had several calls about this issue and fixed at least one so far by replacing the card reader. I applied the workaround above and got the phone working again so I don't understand why a new card reader is going to fix this.

Note 4 seems like it's back working on T-Mobile as of last night.

HI I purchased galaxy note 4 3 years ago in the first time I put him on i has that problem yet
But I live in curacao in the Caribbean and I think that the mother board was not good.
Then I has flight to medellin Colombia with the phone he began working I was glad but when I arrived to curacao from medellin the same problem
Sometimes he is working sometime not
I have the same problem T-mobile N910T

Thanks for the update! I reversed the workaround I applied earlier and mine is back to 4G LTE now.

Any update on this issue?
The N915-T is spotty and I'm trying to figure out why. It was officially kicked off the network by T-Mobile, but it still works. It connects to most towers but not to a particular one. Whenever I'm on that block the network can not be found. If I walk two blocks away it would connect to another tower and I can make calls. If I walk back toward the 'faulty' tower while on the call, the quality would degrade, the call drops and the phone would lose signal.
This would NOT happen with other phones - not even an older Galaxy S2.
This is likely a different issue altogether, as the phone actually connects and works elsewhere. I'm just hoping someone has an idea.
