Before you go.
Staying connected in Australia
Australia is a country of two coverage realities. The east coast cities, the main highways between them, Perth, Adelaide and the tourist corridors are all well served. Everything else, which is most of the landmass, is not. Coverage follows population and roads, so once you are an hour off a highway in the Northern Territory, outback Queensland or the Nullarbor you should assume you have none. A Halo eSIM installs before you fly and starts counting on its first connection after you land. This matters more here than almost anywhere: a long drive between towns can mean hours with no signal, so download offline maps, accommodation details and emergency numbers before you set off. In the cities the picture is the opposite, with dense coverage and near-universal Wi-Fi in cafes, hotels and public libraries.
How much data you'll need
Four to seven GB for a week in the cities, where Wi-Fi is easy to find and distances are manageable. A road trip is different: you will download maps in bulk while you have signal and then run offline for stretches, which front-loads the usage. Budget higher and download more than you think you need before leaving a town.
5G
Our Australia plans run on a network carrying 5G, which is available across the major cities and thins quickly outside them.

Questions? We've got answers.
-
Will I have signal in the outback?
Usually not. Mobile coverage in Australia follows population and the main highways, and large parts of the interior have none at all. Treat any drive away from the coast or a major route as offline: download maps and details in advance, and tell someone your route if you are going somewhere genuinely remote.
-
Is coverage good along the Great Ocean Road and the east coast drive?
Along the east coast between Sydney, Brisbane and Cairns, generally yes, with gaps in the hinterland. The Great Ocean Road has coverage in the towns and patchy reception on the stretches between them, particularly through the Otways. Download the route before you leave Melbourne.
-
Can I call and send SMS on my Australia eSIM?
Halo eSIMs are exclusively data-only eSIMs. While you can engage in voice calls and messaging through WhatsApp, Facetime, and other widely used VOIP apps, traditional phone calls and SMS are not supported.
-
Is my device compatible with this Australia eSIM?
Most phones from 2018 onwards support eSIM, including iPhone XR and XS and newer, Pixel 3 and newer, Galaxy S20 and newer. If it's a reasonably recent phone, you're probably fine. Check our device compatibility page if you want to be sure.
-
When should I set up my Australia eSIM?
Before you leave, while you're still on Wi-Fi. Your plan only starts counting when you first connect to a network at your destination, so there's no cost to installing early. Australia plans run from 1 to 30 days from that first connection. One less thing to sort at the airport.
-
Which networks does my Australia eSIM use?
Each plan lists its own networks and speed policy under Plan details on this page. Which networks a plan uses is set by our network partners and can change without notice, so we show them per plan rather than for the destination as a whole. Your device finds and connects to a supported network on its own when you arrive.
-
Can I top up my Australia eSIM?
Yes, on the fixed-data plans. Running low? Purchase another plan for the same destination from your order page. The new data gets added to your existing eSIM. No reinstall needed. Top-ups are not available on the Unlimited (daily) plans. To keep using data after an Unlimited plan ends, buy a new plan.
-
Can I hotspot with my Australia eSIM?
Hotspot availability depends on the plan. Halo adds no separate hotspot cap and does not meter hotspot data differently, so on plans that support it you can share your connection with a laptop, tablet or travel companion where the local network allows. Hotspot is provided by the network operator in Australia rather than by Halo, so it is not something we can guarantee on every plan.
