SIMIS SIM Tools Bundle

Information taken from the SIM Card, coupled with information collected from the associated mobile equipment, can provide valuable evidence to validate a line of enquiry, prove an association or provide vital intelligence. In todays fast moving high-tech society, it is rare to find any activity that does not involve some aspect relating to mobile telephony. If GSM telephony is involved, a trail of information is waiting to be retrieved from the SIM Card.

What is SIMIS ?

SIMIS automates the process of forensic SIM data recovery. By interrogating the SIM card, SIMIS provides a detailed report in easily viewable HTML format and user-definable printed format for every SIM interrogated.
Unicode support for SMS & phonebook files with alphanumeric elements, allows foreign characters and scripts from any international language to be decoded and displayed.


  • Forensically safe - no facility for the modification of system or user data held on the SIM card.
  • Provides commented RAW data in a standard format for use in third party applications.
  • Correctly handles PIN and PUK entry under controlled conditions.
  • Builds a database with unique file references for each SIM Card.
  • Searchable database with appropriate index categories.
  • Facility to read data from the SIMIS Mobile card interrogation unit.
  • Presents data in a printable format for reports.

Forensically Safe

In accordance with ACPO guidelines SIMIS ensures that no data on the SIM is modified during the read process. The resulting reports are digitally signed with both MD5 and SHA hashes to ensure integrity. A full audit trail data is included in the analysis detailing important aspects from the acquisition process such as:

  • Operator identity
  • Start / End time and date stamp for each process carried out during the SIM interrogation
  • MD5 and SHA checksum of acquired data
