I know very little about computer forensics and even less with cell phones. However that does not stop me from asking the obvious.

If during and investigation If I were to find a cell phone with a sim card. Is there a way to map the location of the individual by the nearest cell tower/s and mutiple locations via forensic software?

If this can be done could it be tracked from the individual traveling from
another country. Example: I go to europe, Asia or middle east could I still map the information even though the phone is used in America.

I undestand this data can be maped with Google maps or another type of software. Has anyone accomplished this.

Any recomendations for software?

Thank You! Very Happy

Eureka.

The short answer is probably not. Most cell phones do not record GPS locations in the phone.


Cell tower pings are a function of getting the information from the carrier, not the phone.

And some carriers do not record the cell tower pings.

I think you are both right.

The SIM doesn't store this info, the carrier does.

It takes a court order to get the records (called Call Detail Records) from the carrier. If you get them, you can plot the locations of the cell towers hit by the phone and map the cell owner's progress on Google Earth.

Paraben makes a product called Point2Point that does just this.

Or, you can just plot the latitudes and longitudes in Google Earth for free.

Actually a SIM Card can contain lcation information for the last cell tower connection. It is incumbent on the provider to write this entry to the SIM Card.

LOCI = 'LOC'ation 'I'nformation

It is EF LOCI in the SIM File System.

www . wrankl. de/SCH /SIM. pdf

Try this document and use the search to find "LOCI"

Agreed....but the OP asked about mapping multiple locations and "tracking".

I certainly agree that the last tower provides some location information. But it isn't a track......

BTW, be sure to keep the phone off the network or that last tower info will be the one outside your lab......
