Method 5: Analyze accounts from the operator (for incoming calls)

If you need to know which SIM the incoming call came from, rather than which it was coming from, the most reliable way is to check the details from the carrier, which is especially true if you use different rates on each SIM (for example, one for work, another for personal calls).

• 📱 Through USSD: Send the command *111# (for MTS), *102# (for Beeline) or *105# (for MegaFon).
• 📧 By email: Some operators send details to the mail upon request (for example, Tele2 does this through a form on the website).

In detail, look for:

• 🔢 Number. SIM-cards (usually listed as a "Subscription Number" or "MSISDN").
• 📞 Type of call: incoming or outgoing.
• ⏱️ Time and date – match with the entry in the call log.

If you both SIM-This is a map from one operator, and in detail, it can be labeled "Line 1" and "Line 2:
