Cellular and SIM Setup

This page applies only to a Pulse Cellular sensor.

Do not open the enclosure without instructions

Many sensors are supplied with a configured SIM. Opening the enclosure or replacing the SIM can affect weatherproofing and connectivity. Contact Grillo Support before making changes.

Before deployment​

Confirm:

  • Cellular service is active.
  • The supplied antennas are installed on the matching labelled connectors.
  • The selected carrier has coverage at the site.
  • The data plan remains active for the expected deployment period.
  • The complete sensor has been tested in Grillo Platform.

Site preparation​

  1. Check carrier coverage at the exact installation point.
  2. Keep antennas clear of large metal surfaces and major obstructions.
  3. Complete activation before traveling to a remote site.
  4. Bench-test with the same SIM, antennas, power adapter, and sensor configuration intended for deployment.
  5. Verify Online status and a current Last seen value in Platform.

If cellular does not connect​

  • Confirm the service and data plan are active.
  • Check that antennas are firmly connected to the correct labelled ports.
  • Test at another location with stronger coverage.
  • Restart the sensor using the normal power connection.
  • Record the Device ID, carrier, installation location, and Platform Last seen value.
  • Contact Grillo Support before changing the SIM or network settings.

Do not test a managed IoT SIM in another device unless the carrier and deployment owner permit it.
