Attach Diagnostic Info
Export your config backup from the web UI (System → Backup), take a screenshot of the Status page, and note which LEDs are lit. This cuts average resolution time by 60%.
📋
Include Your Environment
Tell us: carrier name, APN setting, SIM type (physical/eSIM), deployment environment (vehicle/DIN rail/outdoor), and any recent changes to configuration or firmware.
🔢
Note Your Firmware Version
Check System → About in the web UI for exact firmware version. Many issues are resolved with a firmware update — knowing your current version helps us respond immediately.
