1. Metadata Leak: Each delivery report contains information about your number, shipping time and status, and this data may be collected by the operator for analytics.

2. Additional costs: Some operators charge reports as separate SMS (especially in roaming), for example, on Tele2, the cost can reach 3 rubles per notification.

• 🔒 Turn off reports when they are not needed
• 📵 Use a separate one. SIM-map
• 🛡️ Install. PIN-code SIM-map (in the security settings)
