Coverage details
Mobile device coverage depends on where you are, the device you are using and whether it has an external antenna attached.
5G coverage
The 5G symbol appearing on the device represents that 5G is available on the network in the vicinity of the device. Speed and performance, and whether a 5G device uses the available 5G depends on prevailing radio conditions at your location and whether the device is actively downloading or uploading data. Outside of 5G coverage, 5G devices will continue to use our fastest available 4G, or 3G where 4G is unavailable.
Outdoor coverage
The Telstra mobile coverage checks have been created using tools that predict the likely areas of outdoor coverage. We have not individually tested every particular location within the identified outdoor coverage areas for coverage. This means that while the footprint of outdoor coverage for a particular location is generally accurate, there may be some areas described as being within the outdoor coverage area proximate to locations searched where your device will not work. This is a common characteristic of wireless systems. For example, actual outdoor coverage could be degraded or not existent in specific locations due to certain geographic features or as a result of the device used. Geographic features that may reduce or block outdoor coverage could include formations, such as hills and mountains or even trees.
Indoor coverage
The Telstra mobile coverage checks also provide an indication of the availability of indoor coverage at locations searched, where this is predicted. This is as accurate as we can make it based on what we know. Indoor coverage is highly variable and there may be locations where indoor coverage is indicated, but your device will not work due to local building density, physical structures and building materials. For example, the following things may reduce or block indoor coverage: basements, lifts, underground car parks, concrete buildings, tunnels and road cuttings, steel framing and metallic window film. Devices such as the Telstra Mobile Smart Antenna may assist to improve indoor coverage where it would otherwise not occur.
Offshore coverage
Factors beyond Telstra's control such as the weather, tides, sea conditions and your antenna installation (type and height of antenna above sea level) can significantly influence the actual user experience of coverage, data speed and performance in offshore locations. Public mobile networks must not be relied upon as a primary method of emergency communication at sea.
