To find out the coverage of the Sigfox network in your area, log on to: https://www.sigfox.com/en/coverage.
The blue corresponds to the areas covered by Sigfox.
Purple corresponds to the areas where the network is being deployed by Sigfox. The device will not work outside the blue zones.
However, the map is slightly distorted in altitude. As the coverage is based on ground measurements, there are potentially less white areas when you are out of the relief, and when you are out of the relief (paragliding…).
