Do you expect your everyday electronic devices to remain connected regardless of your physical location?
Deutsche Telekom has expanded its multi-orbit IoT connectivity portfolio by adding Iridium as a satellite partner. The integration allows IoT devices to access the Iridium NTN Direct constellation for reliable, 24/7 coverage.
Why it matters
Satellite connectivity provides essential network resilience for commercial and consumer IoT applications in remote regions where traditional terrestrial mobile coverage is unavailable.
The connection utilizes standard-based NB-IoT technology paired with NESC AI-based voice codecs. Hardware testing successfully used a Nordic Semiconductor nRF9151 development board equipped with a Deutsche Telekom IoT SIM.
The players
Deutsche Telekom
This German telecommunications company is one of the world's leading integrated telecommunications providers.
Iridium
The company operates a global low Earth orbit satellite constellation providing voice and data communication services.
Nordic Semiconductor
This company specializes in wireless technology and provides low-power hardware for IoT devices.
Toyota
A global automotive manufacturer that collaborated on the satellite-linked vehicle voice transmission test.
The details
During a demonstration at Satellite Day 2026, a Toyota vehicle successfully transmitted a voice message using Iridium's satellite network. This capability is now commercially available for Deutsche Telekom IoT customers as part of the multi-orbit offering launched earlier this year.
Timeline
Deutsche Telekom launched its multi-orbit IoT connectivity in February 2026.
The Satellite Day 2026 demonstration took place in September 2026.
The Tech Race
The adoption of Iridium NTN Direct marks a significant evolution in non-terrestrial network integrations for global mobile operators. This move shifts the industry from experimental satellite trials to the standardized commercial adoption of direct-to-device IoT connectivity.
Enterprise and commercial users can now maintain data connectivity in remote areas previously beyond the reach of cellular towers. This improvement ensures that IoT-enabled hardware, such as logistics trackers or remote sensors, remains connected 24/7 regardless of geography.
The takeaway
The move demonstrates that the gap between terrestrial and satellite networks is closing rapidly through standardized IoT technology. Users can expect broader geographic reliability for connected devices as multi-orbit strategies become a standard industry practice.
