Additional Information

If you just received your hotspot, please follow the onboarding must-do instructions sent alongside the tracking email. The most important step is to make sure your hotspot is connected to the ethernet for at least an hour before pairing with Bluetooth and onboarding onto the Helium app. This will ensure your hotspot is on the latest OTA version when onboarding and will eliminate the ‘onboarding key not found’ error that some users encountered due to adding the hotspot while on an older firmware version. Even in those cases, the error will disappear as soon as the hotspot receives the latest OTA.

Important Reminders
  1. If your firewall settings have all of China blocked via restriction in both incoming and outgoing directions, your hotspot will not be able to connect to our device management platform and will not be able to receive the OTA updates.

  2. If your hotspot OTA version is older than, please fill out the form here. The team will check this routinely and update any hotspots that are left behind on a daily basis.
