Explanation

This appears to be a telecommunications/technical question counting parameters in a specific context. The terms are: sim (Subscriber Identity Module), msisdn (Mobile Station International Subscriber Directory Number - phone number), imsi (International Mobile Subscriber Identity), and destination msisdn. That's 4 distinct parameters.
