Iridium · Deutsche Telekom · Toyota
Iridium, Deutsche Telekom IoT and Toyota sent a voice message from a car over Iridium's satellite network for the first time.
what happened
Iridium, Deutsche Telekom IoT and Toyota demonstrated standards-based NB-IoT voice messaging over Iridium's NTN Direct satellite service, sending a test message ("testing, testing, one, two, freeway") from a Toyota vehicle equipped with a Nordic Semiconductor nRF9151 development board and a Deutsche Telekom IoT SIM, using a Fraunhofer voice codec to compress the audio, per a company release distributed on PR Newswire and Via Satellite. The demonstration, held during Telekom Satellite Day 2026, builds on Iridium and Deutsche Telekom IoT's existing roaming agreement; Iridium NTN Direct is set to become commercially available in the fourth quarter of 2026.
why it matters
The demo is an early proof point for Iridium NTN Direct's push into automotive and IoT connectivity, showing standards-based satellite voice working over Deutsche Telekom's existing IoT SIM infrastructure ahead of commercial launch; for Deutsche Telekom IoT customers, it points toward vehicles, logistics and industrial equipment staying reachable once terrestrial coverage runs out.
