I might be abit paranoid about this, but i personally don't like it to supply information to about me to my carrier when ever possible especially after the whole carrierIQ fiasco. So is thinking is there anyway to prevent carrier (tmobile) from identifying my phone?
I heard from a friend that they send the phone's imei number to the tmobile server which is how they identify my phone. Does anyone know which file on the android OS that is responsible for this?

I believe that the IMEI is used to register the phone onto the carrier's network each time you switch on. Thus they can also check if it's a blacklisted phone.

do you know which file in the android system is responsible for communicating with tmobile?

What exactly are you asking.
IMEI will always be sent to the carrier, it's the way the mobile network works. After all your carrier has to register/authenticate you onto their network, if they didn't you couldn't make calls or use data...............
If it's Carrier IQ then get a CIQ free ROM.
If it's something else please state.
EDIT: The more I think about this the more absurd the question is. The carrier will retain logs about SMSs, Voice usage, Data usage. Look and read: http://en.wikipedia.org/wiki/Network_switching_subsystem especially the HLR bit.
EDIT2: The Police etc. also have to have regulatory access to records, no way around that.

any file involved in making and receiving calls, sms, mms, data connection....
there is a concept, Carrier IQ that @gol_n_dal mentions that can allow carriers to access other identification from your device for problem rectification purposes. in the stock rom, htc can also collect some data about what you do as well.
if this is what concerns you, look for a custom ROM which is CIQ free.
There are app in the market to identify if your phone has carrier IQ and also to dissable it, look there to resolve this
As its carrier based (not used by Virgin UK currently after checking with them and using on of the apps on my phone) I suspect that the devs will not do anything about it, but the only way to find out is contact your favorite and ask
The IMEI is part of the radio chip and it cannot be altered or hidden, unless you have a lot of specialized knowledge and equipment. The only phone I've heard of with an easily altered IMEI is some Nokia junk phone they sell in developing markets.

Hi all,
I have a SPV3000 from my work and I lost it for a while so I mentionned it to my manager who is going to state it to Orange to get it blacklisted.
The thing is, after a couple of weeks, I have just found my phone again!
I am not feeling I should mention it again to my boss as it sounds really ridiculous and he was kind enough not to argue on the loss. But well, now I have a phone fully working which IMEI code will soon be blacklisted by the 3 main operators in France running a common database on the subject (in case of phones stolen). I may send my phone to a friend abroad who will certainly be able to use it there but is there any tricky solution to be able to use it in France?
What is this IMEI code exactly and how does it work?
BE SURE I AGREE WITH THE IDEA OF BLACK LISTS TO AVOID SO COMMON AGGRESSIONS JUST FOR PHONES...
You may send me private posts in case you are reluctant to have this kind of information largely communicated.
Hi marcel06!
IMEI is kind of like a serial number which your cell company sees.
If you haven't noticed, there is a wiki link under the word for details.
There are no tricks when it comes to IMEI. There are ways of changing it, but that is illegal in most countries.
Because IMEI identifies your phone, thieves could change their phone IMEI to match yours so you would pay for calls made from other phone.
If you really want to use the phone again, you should report that it was found so they won't blacklist you.

Oh.. no. I'm not sure about those pre-SIM period phone. But I'm definately sure that now, for phones that are using SIM cards, you are not able to charge to others account using IMEI. The controlling mech is the SIM card, the billing information is in the card, not the phone. But the operator will have the power (as I've heard) to disable/track phone by IMEI.
Is anyone aware of something like this, or what would be involved?
Before I am assaulted for asking this question, the reason it is of interest of me is not because I have a stolen phone, but T-Mobile US is now blocking certain data plans by identifying handsets by IMEI number.
I recently bought a unlocked HTC Magic and inserted my SIM card which worked just fine on a T-Mobile Shadow (HTC Juno). The data plan worked for a few hours, and then was blocked because the T-Mobile network recognizes these phones IMEI as a G1. The data plan I actually had (per the recommendation of a T-Mobile rep), was a Blackberry plan with an International E-Mail Roaming package (as I travel frequently internationally). After many hours on the phone with them trying to find a solution, T-Mobile determined there was not a solution and I could not use the HTC Magic with my plans.
Given these changes on the T-Mobile US network are relatively new, and the imminent growth of Android handsets, I believe there could be a market for such an application.
Lastly, according to my research, in the United States, there are no laws that exist which bar changing of an IMEI number. So, to all of you vigilantes out there, please leave law enforcement up to the police.
Anyone have insight into this?
from what i understand, every time the phone is booted up, it connects to the carrier to let it know what your IMEI is, then associates your account(your number, sms, email, etc) to that imei. if you change it, you could run the risk of picking someone else's imei and start receiving some of their things(from what i understand, although i could be a bit off.) but from the bit of info i have read online about it, its similar to MAC address Spoofing on a pc, in respects to what need to be done and how and what it works for.

The only phone i know that can reveal an unlock code while rooted in the new samsung galaxy s2,... Personally i dont know why its such a hard crack for developers...
root helps...
it is only the network unlock code, that we need to find hidden deep(usually encrypted or in byte code). Root helps to access these files.
its obviously carrier related, this is why they sell you the phone cheap, because we're tied to their network.
most carriers, and phone manufacturers will give it to you after a few months. Or tell them youre going overseas.
root doesnt really matter to the network.
It's complex. The device's radio (the actual "phone" part) isn't easily manipulated in a way that can give you a SIM unlock. It usually needs either hardware or a code. Software-only methods are very rare, so far I only heard of some ZTE devices, the abovementioned Samsung device, Desire and Desire Z.
Galaxy S2 only could be unlocked this way because the unlock codes leaked into the phone during manufacture.
Is there any more input?
Essentially, you cannot access the radio memory because of the way it is designed to interface (on hardware level) to the rest of the phone. Very rarely do manufacturers make mistakes that do allow to alter it somehow. This design is done on purpose, to let the network operators lock the phone in as well as to prevent your Joe Average from downloading a tool online to unlock it without paying.
I don't really know more than that. If you want more info, most likely you will need to use Google.
I have tried Google but I can't get a straight answer.

Dear forum,
let me just go straight to the point:
My Galaxy Nexus was stolen at work last friday. I tried to use some tracking software like Plan B but without succes, the SIM card had been changed allready.
Now here comes the part that gave me some hope.
When I went to My (Gmail) Account at the Android Market today (using my desktop), I noticed 2 things:
- First thing is that the record from the column "Carrier" has been changed from "Vodafone" to "KPN', so I think I can assume here that someone put another SIM card in it.
- Also at the column "Last Used" I see "February 13, 2012", which is yesterday (monday).
I was really wondering if there is a workaround or something to get more information (like the phone number of that SIM card?) than just the carrier of that SIM card and when it was last used?
Thanks in advance~

During the night push a remote lock app to the device, if they haven't changed the google user login by then. Then just lock the device. If the app shows it set a screen message offering reward for return. Better still make it scream while at work tomorrow.

The thing is, I only work at fridays and saturdays. I also think that the person is smart enought to not bring the phone to work when I'm around.
I thought maybe if I could get some more information with a workaround, I could catch the thief myself instead of waiting for him/ her to give it back (which probably isn't going to happen).
I hope you informed your managers.
You could have a look through the available apps in the market see if there is anything you can use to lock the phone remotely and or push some really nasty messages to it. If you ain't using why should they get the use of it think there may be some way of remotely wiping the phone aswell. Then at least it would be of no use to the thief anyway. Sorry I can't be of more help. I allways make sure I activate any built in phone finder and instal lookout, so never really had to deal with the issue

Note that the phone is stolen and SIM card has been changed allready. As far as I know you need to configure Prey on the phone itself, so not really remote like Plan B.
I'm still curious if there is a workaround to get more information about the SIM card than just the "Carrier" and "Last Used"?
Like.. are those the only two things that get stored or is there more information about the SIM card that I could get without having the phone itself?
If you have the IMEI you can contact your network and ask they put a block on the phone, a lot of the time it also blocks it off other networks as well.
i think the info about the sim like its number is by far more important than map location because if you got the thief's number then you can report that number to the police and mobile network .

This is pretty much what I'm aiming for since I allready have contacted the police and gave them the IMEI of the phone. They said like something like "We'll see what we can do", but I thought there would be some workaround (yeah I'm using this word alot) to get more information of that SIM card.
I think I can assume that the column "Carrier" which is shown on the screen, is read of the SIM card?
Question is, if anything else is shown somewhere in my Gmail (since it's linked to my Galaxy Nexus) or at the Android Market or something that might be of help?
do you know that mobile carriers can identify everything to a handset with just an IMEI
i don't know what is the procedures in your country but i think you should call that carrier and ask for directions especially if you have a proof of purchase or something similar

My question is, did you inform your carrier? Here, when that happened to my friend who wasn't too tech saavy, I called his carrier, had the phone blocked right away, and told them what network it was on via the same information that you received via email. The actually contact the manufacturer and the police and were able to track it down on their network, find the phone and press charges. That IMEI number is huge as it tells the carrier what exact tower the phone is connected to. In densely populated areas, that's 1-2km max. Cross reference the people at work that live in that area and boom. Done like dinner.

Yeah I know that, but I called both the police and my carrier and gave them my IMEI and asked if they could do such thing.. and both said that they can't do such a thing, ONLY if the phone has the original SIM card... I think they just don't want to help me at all.

The service fault does not exist. Because I replaced several SIM cards without signal, and I replaced these SIM cards with other mobile phones, all of them can use the network normally. As for the loss of configuration, I don't know how to operate it. I have been using it for several days. There is a signal. Suddenly, there is no signal one day. I have a signal from HO2, update to color13, and suddenly there is no signal at color13。I can't get the network when I change the system back and forth in Ho2.color13.oos.

Unless you and I referring to apples and oranges. Your issue has nothing to do with which operating system you are using or have updated to.
-- Reprovisioning resets your connection to the server and sets everything that reps can modify back to default settings.
-- Most carriers place the blame on user meddling on their device causing misprovisioning(s).
Reprovisioning refreshes the data on the UICC/SIM and APN settings.
It can also mean them changing the QCI settings on the UE and UPF at the core layer (meaning changing / presumably increasing the allowed speed of your service).
In simple terms, provisioning is the process of preparing and equipping a network to allow it to a provide service to its users. SIM Card provisioning is a process to activate said SIM and services before it is used by a customer.
Reprovisioning of a SIM is nothing but repeating the process from scratch.
In the event that you feel that it could be something else besides the SIM and/or IMEI, feel free to enlighten me.

I'm wondering if he's trade-in a stolen device or not. Since due to TMO's policies ( As mentioned in other topic, I have KebabTMO ) the device will be network locked permanent. And as I did lots of research on this matter with 8T, the only solution is to ditch the modem and replace with another one, then force EDL flash Global fw to convert it to global.
Using tools ( even Qualcomm Tools or other pro tool specific made for OP devices or to work with deivce's modem are both useless in this case, I even used QXDM, QCAT, along with QPST )

The general consensus it to perform a factory reset.
-- Take a deep breath, clear your mind and prepare to contact the network provider with explicit details.
-- You initially stated that you exchange phones with others.
-- You need to check to be certain that the ESN is cleared "for take-off".
A clear/clean ESN indicates that it is activated properly by the service provider. An unclear ESN refers to a phone that is either still activated, or lost/stolen.
ESNs might be “bad,” which means the carrier has blacklisted the phone at a moment's notice.

In this case you should have gotten a Chinese OnePlus 8. T - Mobile and other American carriers are picky with devices being used overseas, and there are often compatibility issues with doing so.
Often times your phone might not be able to connect to the cell towers in China because the cell bands may be different. This was the case for another Chinese user with the IN2019 (Verizon model) who couldn't connect at all. Your best bet would be to just get another phone or desperately try using the global or Chinese ROMs in the hopes of getting a connection.
