Phone signal and eSIMs on Australia's famous routes
TrailSim has analysed 4 routes that cross Australia — 1,353 km of trail and road, checked against the ACMA licence register. Across those routes, TrailSim's model puts fast 4G/5G data on 54% of the distance, with 26 dead zones of 2 km or more mapped. The best-covered is Great Ocean Road (B100) (89%); the weakest is Overland Track (Cradle Mountain–Lake St Clair) (0%). 1 more route in Australia is in the catalog without a published report yet.
Australia routes with a coverage report
Fast 4G/5G share is the part of the whole route with usable data on the featured plan's networks (a TrailSim model estimate, not a measurement); dead zones are continuous stretches of 2 km or more with no signal on them. The km column is the distance inside Australia. Every order on these routes includes the report (PDF + GPX).
| Route | km in Australia | Fast 4G/5G | Dead zones | Dead-zone km | Typical days |
|---|---|---|---|---|---|
| Great Ocean Road (B100) | 240 | 89% | 3 | 25 | 3 |
| Great Ocean Walk (Apollo Bay–Twelve Apostles) | 96 | 81% | 1 | 16 | 8 |
| Bibbulmun Track (Kalamunda–Albany) | 960 | 46% | 21 | 517 | 55 |
| Overland Track (Cradle Mountain–Lake St Clair) | 57 | 0% | 1 | 57 | 3 |

Frequently asked questions
Which eSIM works best for hiking or driving in Australia?
It depends on the route: each of Australia's networks holds in different places, so TrailSim compares them along each route and features the plan whose networks cover the most of it at a sensible price — Great Ocean Road (B100) is the best-covered of the 4 analysed Australia routes at 89% fast 4G/5G data (TrailSim estimate). Every Australia route page lists current plans and, where a report exists, the dead zones with GPS coordinates.
Is there phone signal on hiking trails in Australia?
Across the 4 Australia routes TrailSim has analysed (1,353 km inside the country), the model puts fast 4G/5G data on 54% of the distance, from 0% on Overland Track (Cradle Mountain–Lake St Clair) to 89% on Great Ocean Road (B100). These are estimates from the ACMA licence register, not guarantees; 26 dead zones of 2 km or more are mapped in the route reports.
Do the plan days start when I buy?
No — on first use. Installing the TrailSim eSIM and connecting in Australia starts the clock, so you can buy weeks ahead. Uninstalled eSIMs can be refunded within 14 days.
