Cell Modem Connection Troubleshooting - Suspected Poor/No Network Coverage
Background
Section titled “Background”This guide is a landing page for Cell Modem Connection Troubleshooting, specifically for suspected cell network coverage issues.
NOTE: The cellular network, aside from our ability to connect to it, is generally outside of our control. The cellular network’s reliability will vary by location, and along the flight path of an Aircraft.

Wait 10 minutes and then resend the mission. Did the issue resolve?
For example:
- Aircraft in a Dock or Dock tower experience higher occurrences of cell modem connection issues.
- Deliveries to a specific address or Zipping Point fail frequently for cell modem connection issues.
- Flights to or through a specific area fail frequently for cell modem connection issues.
