Features
How Telstra Satellite Messaging works
Coverage beyond the mobile network
Satellite-to-mobile technology complements Telstra mobile services by supporting satellite messaging in most parts of mainland Australia.
Uses phone’s text app
The service can send and receive texts via the phone’s text app when connected to a Starlink Direct to Cell satellite. This may take longer than when connected to the Telstra Mobile Network, depending on location, device and satellite position.
Our satellite network is available in most outdoor areas on mainland Australia and Tasmania, excluding the Australian Radio Quiet Zone in Western Australia and remote offshore territories and islands of Australia. Not suitable for use in emergencies. Does not support one-way messaging e.g., emergency broadcast messaging.
How it works
How to use Telstra Satellite Messaging
-
Check you’re satellite-ready
You need a compatible phone with the latest software, and an eligible Telstra Adaptive Mobility plan with the Satellite Messaging add-on. Check before you leave the Telstra Mobile Network area.
-
Go outside and look up
When beyond the range of the Telstra Mobile Network, make sure you have a clear line of sight to the sky. Your view must not be obstructed by things like buildings or vegetation.
-
Look for ‘Telstra SpaceX' on your phone
In most parts of Australia, a compatible phone will automatically seek a satellite connection once beyond the range of our mobile network. When the phone is connected to a satellite, it will display 'Telstra SpaceX’ on the network banner.
-
Send your text
Now you’re ready to send and receive satellite text messages to standard Australian and international numbers.
Telstra Satellite Messaging is an intermittent service. Some messages may take a few minutes or longer to send and receive, depending on location, device and availability of Starlink Direct to Cell satellites. Does not support one-way messaging e.g., emergency broadcast messaging.

About Telstra Satellite Messaging
Telstra Satellite Messaging lets eligible customers send and receive text messages from their compatible mobile phone via satellite when beyond the range of our mobile network.
Your experience with Telstra Satellite Messaging will be different to the mobile messaging experience. Some messages may take minutes or longer, depending on your location, device, and satellite position. To improve the experience, ensure your messaging app remains open while using Telstra Satellite Messaging.
When you're out of mobile network range, your compatible phone will automatically seek a satellite connection if you're outdoors with a clear view of the sky. Once connected to a Starlink Direct to Cell satellite, the phone will display "Telstra SpaceX" on the network banner.

No. Do not rely on Telstra Satellite Messaging for help in an emergency. SMS is not suitable for warning people about serious risks or asking emergency service organisations to come to someone’s aid.
Telstra Satellite Messaging and Apple's Emergency SOS via satellite are two different services and use distinct satellite constellations.
Apple’s Emergency SOS via satellite is available on iPhone 14 or later (all models) and can be used to text emergency services when you're off the grid with no cellular and Wi-Fi coverage. For more information, please visit Emergency SOS via satellite on apple.com.
Telstra Satellite Messaging is enabled by Starlink Direct to Cell and complements the Telstra Mobile Network to allow Telstra customers with a compatible device with the latest software, and Upfront Mobile Plan to send and receive texts from most areas of mainland Australia. It is not designed to be an emergency service, as you cannot text Triple Zero (000) directly from Telstra Satelite Messaging.

Things you need to know
Requirements
Satellite Messaging requires an eligible Telstra Adaptive Mobility plan with the Satellite Messaging add-on, and a compatible device with the latest software update (see the device checker above).
Coverage and availability
Satellite Messaging is available from most outdoor areas in mainland Australia and Tasmania (excluding the Australian Radio Quiet Zone in Western Australia and remote offshore territories and islands of Australia). To access the service, you will need to be outdoors, out of mobile network range, and have a direct line of sight to the sky. Don’t go outside to use Satellite Messaging if conditions aren’t safe for you to do so. Satellite Messaging is an intermittent service. Satellite Messaging can only be used to send and receive SMS to standard Australian and international numbers. You can’t send or receive MMS or instant messages that require the internet such as WhatsApp, make or receive video or voice calls, access data, or send or receive SMS while overseas. Some messages may take a few minutes or longer to send and receive, depending on location, device and satellite position.
Not for emergency use
Don’t rely on Satellite Messaging for help in an emergency. It can’t be used to call or text Triple Zero (000), doesn’t support one-way messaging such as emergency broadcast messaging, and isn’t suitable for telling or warning people about serious risks or asking emergency services to come to someone’s aid.
