How do the Astrocast Satellite IoT data plans work?

We offer a combination of standard plans, adapted to an expected volume of data transmission by modules that are in operation. No fee is applied for switching between the plans, allowing users to control their spending more easily.

Astrocast offers minimum contract lengths that vary between three to five years, to cover long-term operations with no activation fees for the modules accessing our network. For more information visit our Satellite IoT data plans article.

How can I send downlink commands to my assets?

Downlink commands can be sent to your assets manually in the Astrocast portal, or via the API. Find out more on the Astrocast 101 video “Send a downlink command to the Astronode S“.
