Hi everyone
I read a lot about tracking mobile phone with the Cell ID and neighbour Cells via GSM service [1]
the GSM protocol can initiate a scan of the neighbor cells and their signal strength which leads to a position accuracy <100m
Does someone know more about it?
second using silent/stealth sms to receive cell id [2][3][4] (no English infos found you got censored? ) google translate if you don't speak German...
this special sms type does not show any information on your handset, its silent! So you can't detect when you receive one.
On which level of the phone is this behavior handled? Baseband/Radio or the OS?
As example on Android you get the kernel source and all the source of the standard apps running on it. Probably a way modify the way it reacts if it is in this part of the code.
The Radio/Baseband is NOT?[needs clarification] open source, so no chance here?
Is there a way to detect this behavior?

Hi mopodo,
just FYI, "silent sms" can be sent wia WM, a tool called "Hush SMS" allows this.
And there is no information carried via this SMS back to the originator.
Cell-ID based tracking can only be done by the owner of a cell tower, i.e. the operator. And since this requires lots of time, they (regularly) only do this on request of the prosecution.
But I do not know more about this topic, the above information is what I (supposedly) know about this.
Regards

Welcome to the forum! Tell us a little on what you know about CITA?
Hi! Let me introduce a tiny app, available in English in the moment.
This program shows a small info window during incoming/outgoing call. It contents country, region, city (or mobile operator) and LOCAL TIME in that place (worldwide)!
See latest comments and screenshots on cyrket (I'm not allowed to insert links)
Detailed popup customization is supported
The phone base I collected and created (many errors there were fixed by hands) was only available in Russian, but today I released English base, made with help of Google Translate
I know, such translation is buggy (but still much better I expected). I hope you'll help me and other users to have a complete and accurate information about calls - just email me right from the program menu about any issues or comment here.
World time also changes (for example, Russia lost two time zones this March) and if you find any error - post here or email me
You don't need to download phone base. You may download its latest version from the app, but if you want to do it manually, unpack the zip to the sdcard's root
How accurate does it get? I don't get many international calls, but might be useful to know where a landline call from within the UK is coming from?
What happens with mobile calls from with the UK? I assume no detail at all then?
it covers both landline and mobile network all over the world, where it is possible to distinguish between numbers by area codes. just try =) there are more than 25000 records in the base

Hi. How do you set this up?
I have placed my Country Code (00351) and set GMT to +1 and when I call from my desk to my phone, it says it's a call from India ...
afaik, country code cant starts with zeros. Please, provide full number (you may hide last four digits) and right country for you I'll check and write settings here
Erm, I think techinally it either starts with two zeros, or a + but you're asking for a single number?
For example, UK is either 0044 or +44
wow. That is new for me. I know that with one leading zero start local calls. And you say two zeros replace + . hmmm. try left country code blank, that may help, I think. and if not, please, type whole number without four last digits
Not sure if this is already obvious but as there seems some uncertainty. AIUI the correct way to state an international number is to prefix it with +. To make a call, the plus sign is replaced with the two (or sometimes three or four) digit international access code which depends on the country one is placing the call from. For Europe this is 00, for the States, 011 etc.
I'm in Portugal, and my number is +35193233xxxx. I have tried leaving it blank, but by default leaves a 7... tried with 00351, with 351 and when calls are incoming still stays it's from India.
I'll wait for further clarification and if nothing happens I'll un-install it.
By the way, it doesn't let me use the +.
Thanks
okay, and what was the incoming number? what it was looking like on the call screen? country code preset replaces leading zero or eight digit. so it doesn't interfere number detection in you case I think

The incoming number was looking like this: 91811xxx
It's a mobile number from Vodafone.
Just got a call from Germany, and it identified the Country and city allright. Seems that it doesn't work for calls inside Portugal only...
i see eight digits and no country info in this number. if there are seven digits program says local call and do not provide any information (because there is no trusted information) in eight or more digits it tries to detect country code. it replaces leading 8 or 0 with country code from the settings - for example local russian mobile calls may look like 8916xxxyyzz - we replace 8 with country code 7 and identify it with MTS - the program even say region or city based on x or xx or xxx in the example above. but in your situation I have no idea how to detect that the call is local and country code needs to be put before the number =( I've never heard that income mobile number may be in the format you wrote - it should start with plus sign and country code or 8 or zero (Ukraine, Moldova). I'm whirled

Any chance you can convert the database into something human-readable? I'll be glad to cross reference a bunch of Southern California area codes and prefixes so that you can get some more accurate data there.
Also, a program similar to yours got hit with a cease & desist a few months back by some patent trolls because they supposedly hold a patent on this very thing. You're in Russia though so I dunno if their reach extends to you. Just thought I'd give you an FYI.

please, email me a t r a n t . s g @ g m a i l . c o m (or from the program menu) to discuss db elements, thanks in advance.
and yeah... i've read that stuff and even contacted the author...
But, my program is better now, I think =) And I will hit 10000 downloads, I hope. That will be enough, I think, for my efforts and hand-made db =))
Uninstallation
How do i uninstall de database, can't find it but i takes 3 mb of internal memory. Anyone has a suggestion!!

Just remove the DB app. There is no way to leave DB app and remove the DB, android OS restriction (can't modify signed apk on the device)
uninstallation
So when i uninstall WorldCallPlaceAndTime.apk than de database will be removed from my internal memeory?

Sure, man! Do it right now!
I live in a country where it is obligatory to dial long distance company prefix for calling other areas and countries, thus I can´t have all numbers stored in an international standard notation. Like I can´t store a UK number like +44 1273-701648, I have to store it like 00XX441273701648 (where XX is a two digit long distance company code, like 23 or 41 ). Same with in-country numbers - I can´t store them neither in international nor in regular local form, for example - I live in area code 011, so to store a phone number in area code (081) 3421-3266, I have to store it as 0XX8134213266 (where XX is a two digit long distance company code, like 23 or 41 ). At the same time, I have to store numbers in my own area without any prefix at all. So far so good, as long as I don´t leave my area or country.
If I will go to another area, like (081) - I will have to cut off all 0XX81 prefixes since I will be in roaming locally there. At the same time I will have to add 0XX11 to all numbers from my native area code. Worse - if I will go to an area from which I have no numbers stored let´s say 019, I will have to keep ALL locally stored codes, like 0XX81... BUT also add 0XX11 to all phones from my native 011 zone.
When roaming abroad it is somwhat easier - I´ll have to cut off 0XX and add country code +55 to ALL numbers. But also I´ll have add area code 11 to all phone numbers from my native 011 zone.
When I was using WM6.5, Magicall by Mobiion was able to do it for me. Is there anything similar under Android?
Did you check android settings?
There is an option for automatic prefixes, atleast on my i9000.
It might be possible to make a widget that gives quick access to enable/disable the prefixes.

Nothing like this on my X10 mini pro. At least visibly, but I´ll try to look into it. Thank you!
Thank you everyone for feedback. I was advised to try out Prefixer and it is exactly what I needed.
This is one of the phone settings in my DS.
Can anyone explain exactly what it means ?
I know the basics of roamiing but this one is beyond me.
A google search on that phrase reveals nothing ;-(
- Thanks !
It adds the international dial code to numbers in your contacts list when you're roaming .
Eg , if your phone is set up in Ireland , it adds +353 to the beginning of any dialed numbers when roaming .
It adds +44 to UK based phones when roaming.
It can be useful if you don't have your numbers saved with the internatiomal dial code .
Click on "home dialing" to see more options.
Hope this helps.

That's very useful to know for when I go on holiday.
Actually, I have set OUTLOOK to include +44 on all my numbers as "UK", so I probably won;t need to use the function - But at least I now now ;-)

My new BlackView 9900 Pro will connect to the carrier's network, but the built-in MEID is invalid on serveral carrier's websites. I know it can be changed, but I don't know how to generate a valid one.
Can anyone help?
Thanks,
Johnny
I wonder that why the built-in MEID is invalid on the carriers' websites.

I'm working with my second (NEW) purchase, both from BlackView. They both have the same invalid MEID. No response from their support. It seems to be a great phone, if only I could use it as a phone.
