Do you trust satellite technology to provide reliable mobile coverage in your area?
OpenSignal has released a global map identifying locations where direct-to-device satellite connections are active. This technology allows compatible smartphones to communicate with low Earth orbit satellites when conventional mobile networks are unavailable.
Why it matters
Satellite technology helps bridge critical mobile coverage gaps in remote Australian regions where building terrestrial network infrastructure is not commercially viable. The map highlights the increasing adoption of these services as the nation works to meet new connectivity standards.
Telstra reports more than 200,000 daily satellite connections and over 26 million total messages sent using the service as of July 2026. The government plans to auction the 2GHz mobile satellite services spectrum before the end of 2026.
The players
OpenSignal
This is a mobile analytics company that specialises in mapping and measuring network performance and connectivity worldwide.
Telstra
This is a major Australian telecommunications company that provides a range of voice, mobile, and internet services.
Optus
This is the second-largest telecommunications company in Australia, offering mobile and broadband services.
Starlink
This is a satellite internet constellation operated by SpaceX, which provides satellite-based internet access globally.
Australian Communications and Media Authority
This is the Australian government body responsible for the regulation of broadcasting, radiocommunications, and telecommunications.
The details
Direct-to-device connectivity relies on advanced antennas within compatible smartphones to link directly with satellites in low Earth orbit. These connections automatically activate only when terrestrial mobile coverage is non-existent, ensuring continuous communication in isolated areas.
Timeline
2023: Optus signed a satellite partnership deal with Starlink.
June 2025: Telstra launched its Satellite Messaging service.
Early 2026: ACMA revised mobile coverage standards for Australian telcos.
July 2026: Telstra released data on Satellite Messaging service uptake.
October 2026: The Universal Outdoor Mobile Obligation was enacted into law.
The Tech Race
The deployment of satellite-to-mobile technology marks a significant departure from reliance on traditional ground-based cellular towers. This evolution is driven by the Universal Outdoor Mobile Obligation, which forces industry players to address geographic coverage gaps that terrestrial systems cannot reach.
Users with compatible smartphones in remote areas can expect improved messaging reliability where traditional mobile coverage fails. This technology provides an essential backup for communication, though users may encounter limited service performance until infrastructure matures by 2027 or 2028.
The takeaway
Satellite messaging is increasingly becoming a standard feature for those travelling through remote regions without terrestrial cellular signal. Consumers should check if their specific smartphone model supports direct-to-device satellite connectivity before relying on it for emergency communication.
What happens next
The Australian government is scheduled to auction the 2GHz mobile satellite services spectrum before the end of 2026.
