In a major leap forward for mobile connectivity, Telstra has officially launched Australia’s first satellite-to-mobile text messaging service, allowing users to send and receive messages beyond traditional mobile network coverage. This groundbreaking service, delivered in partnership with SpaceX’s Starlink, is designed to bridge long-standing communication gaps in regional and remote parts of the country.
Texting Beyond the Towers
The new satellite messaging service is initially available exclusively on Samsung Galaxy S25 devices, with plans to expand to more devices, including iPhones, in the near future. Messages are transmitted using low Earth orbit (LEO) satellites, meaning users can send SMS and emojis even when far from mobile towers, as long as they have a clear view of the sky.
As Telstra’s Channa Seneviratne explained, the service is currently limited to basic text messaging, but will evolve to support voice and data services over the next 1–2 years. This aligns with the federal government’s broader push to expand rural and regional coverage.
Why It Matters
Australia’s vast geography has long posed challenges for mobile infrastructure. This service promises a new layer of resilience and safety, especially for travellers, farmers, emergency services, and outdoor enthusiasts in areas known as mobile “black spots.”
Communications analyst Graham Lynch told the ABC that the ability to send a text from anywhere outdoors using a regular smartphone is “a game changer”, especially in emergency scenarios.
How It Works
Here’s a quick breakdown of what you need to know:
- Device required: Samsung Galaxy S25 (for now)
- Coverage: Anywhere with an unobstructed view of the sky
- Message types: Text and emoji only (no MMS or images)
- Delivery time: Can vary depending on satellite availability
The service leverages Starlink’s satellite constellation, which orbits much closer to Earth than traditional satellites, allowing for faster and more reliable message delivery compared to older satellite phone systems.
What Are Your Other Options?
If you’re not ready to upgrade to a compatible device or need full two-way satellite messaging right now, here are a few standalone options already available in Australia:

What’s Next?
Telstra’s entry into the direct-to-device (D2D) satellite messaging space reflects a growing trend among telcos globally. As the technology matures and becomes standard across flagship smartphones, we can expect greater accessibility and affordability.
It also raises questions about data privacy, competition, and pricing models, all of which will become more important as satellite services become an everyday part of mobile communication.
For now, though, Telstra’s new offering is a welcome first, and could make a real difference for those living, working, or exploring in Australia’s most remote regions.
