KEY FEATURES • SIM card asset management: Manually enter ICCID, phone number, carrier, country or region, purpose, and notes. • Expiration reminders: Record activation and expiration dates, renewal cycles, and reminder preferences. • Multi-device sync: View SMS, app notifications, and call records synchronized from source devices you authorize. • End-to-end protection: New message titles and bodies are encrypted on the message-source device using AES-256-GCM. Content keys remain in secure storage on your devices. • Device management: View connected devices, online status, recent activity, and synchronization status. • Account security: Email verification, anti-bot login checks, password recovery, recovery keys, and permanent account deletion. PRIVACY AND PERMISSIONS Message collection is off by default and requires explicit permission for each capability.

SimDock does not provide eSIM downloads, switching, activation, LPA, APDU, or carrier services.
