Retrieving IMEI, IMSI, Network Info (Cell Id, Location Code) on 3rd Edition.
27 Dec 2006 - 11:47
Keywords :

Retrieving IMEI, IMSI, Network Info (Cell Id, Location Code) 3rd Edition.

In the 2nd edition there are many ways to retrieve the IMEI and IMSI. The one popularly used is the 3rd party “MobInfo Dll”. In Series 60 3rd edition there is no such third party Dll. Instead “CTelephony” needs to be used.

I've seen lots of threads for 2nd edition, but did not get good pointers for retrieving these parameters for 3rd edition.

Following is my contribution on how to retrieve IMEI and IMSI. Along with that you can also use this code to retrieve network info (Cell Id, Location code) It can further be extended to retrieve other network info.

Note: This piece of code requires "ReadDeviceData" Capability.

You can further extend the above code for retrieving other network information.

Hello all,

I write with regards to the authors' following comment:

"You can further extend the above code for retrieving other network information."

Any links to what these "other network information" might be would be greatly appreciarted.

Best, wirefree101

Hi

I would like to ask, is there any way we can fetch these informations regarding the IMSI or network informations without the capabilities.

Regards

Submitted by vinay on Fri, 2007-03-02 07:42.

As I said earlier you can retrieve the MCC and MNC values.

The signal strength can be retrieved using "CTelephony::GetSignalStrength()" Go through the methods of CTelephony class to see what all information can be retrieved.

How we can fetch the area code ( cell info ) in the third edition phones. Is it possible?

Submitted by Deepak Agharkar (not verified) on Thu, 2007-02-22 17:14.

All this information on the IMEI code sounds good. But how can one track a LOST or STOLEN mobile by using this IMEI code ? Is it possible to track the SIMcard number being currently used based on submitting this IMEI code to the Mobile Manufacturer ( Eg. Nokia, Samsung , Motorola etc)? Or can we track the cell phone service provider ( BPL, Hutch, Airtel etc.)in such a case and what is the procedure ?

Submitted by vinay on Fri, 2007-03-02 07:03.

Well, Whenever a mobile registers to the network the IMEI number is sent from the handset to the mobile station during the handshake. The EIR (Equipment Identity Register) maintains the list of mobiles which are identified by their IMEI. An operator can maintain a Gray list which lists the IMEIs that need to be traced, and/or a Black list which lists IMEIs that need to be blocked.

For deeper insight, go through this link, http://en.wikipedia.org/wiki/GSM_core_network

hi there,
i'm newbie in symbian programing.

i'm trying to get cell_id +signal strength (not only the one connected, but few others)

if anybody knows anything let me know

Thanks

When i use unprotected UID, i get the value for cellid and LAC.
But when i use Protected UID the value for cellid and LAC i get is 0.
How to resolve this? I need to use protected UID.

hello every body,
I am new to this site, and found it very interesting. You guys are giving very useful informations about new mobile technology. But can you tell me some useful informations on this topic.
1) Is this programming is for PC's?
2)What kind of system requirements do we have to run this program?
3)In which computer Language this program is made?
4)Can we locate the IMEI no of the mobile ,whom i only know the number.
5) Can i check the location of the mobile with the help of this program.

Please provide thises informations, I'll be very thankful to you.

Regards,
Dheeraj

Nice article. I normally use the *#06# to find the imei number, & i used these procedure to unlock my mobile from http://www.mobile-unlocker.com/ but here to find the imei using java codes is very useful. Thanks for this information.
