SIMcon is a forensics software tool that can generate information for mobile device investigations. In Hands-On Project 12-1, you examined SMS messages on two phones that had been generated by SIMcon.

In this project, you view the report with additional details that was generated.

Be prepared to do research for this assignment.

1. Start Notepad, and open Report_Nau's_phone.txt. Start a second instance of Notepad, and open Report_Sebastian's_phone.txt.

2. As you examine the reports, find definitions for the following items: Inter- national Mobile Subscriber Identity (IMSI), PLMN selector, HPLMN search period, and Cell Broadcast Message Identifier (CBMI). Note any other items of interest.

3. Explain what "SIM Phase: phase 2 - profile download required" means.

4. You notice "Originating Address (TP-OA): 264813358947" in the report for Nau's phone. The number breaks down into 264-81-3358947. Explain what the first two numbers-264 and 81-designate.

5. Explain what the following originating addresses mean:

• Originating Address (TP-OA): 123

• Originating Address (TP-OA): 131

6. Next, compare the two files. If you didn't complete Hands-On Project 12-1, create a timeline of the SMS messages.

7. Write a report with answers to the preceding questions, and include any conclusions you drew about the messages' contents.
