Our recommended eSIMs for Australia
Roaming to Australia is expensive on most home plans, and an eSIM is the simple fix — buy online, install before you fly, and keep your home number for calls and codes while the travel plan carries your data.

Coverage in Australia
Coverage is strong along the populated east and south-east coasts and in the cities, as travel eSIMs use Australia's major networks. The Outback and remote interior have large gaps for every network, so plan offline maps and check coverage if you are heading inland.
How much data do you need?
- ◆Light use (maps, messaging): 1–3GB per week.
- ◆Normal use (social, navigation, photos): a 5–10GB plan.
- ◆Long road trips: a larger data allowance, plus offline maps for the interior.
Getting connected on arrival
- 1Buy your plan before you fly, while you still have your home connection.
- 2Install the eSIM when prompted (scan the QR code or tap install in the provider's app), and label the line so it is easy to find.
- 3On arrival, turn the travel eSIM's data on and enable data roaming for that line.
- 4Set your home line to 'data off' so you are never billed for roaming, and keep it active for calls, texts and two-factor codes.

Does an eSIM work in Australia?
Yes. Travel eSIMs connect to Australia's major networks, with strong coverage along the coasts and in cities. Your phone must support eSIM and be unlocked.
Will I have signal in the Outback?
The remote interior has large coverage gaps for every network. Stick to main routes for connectivity and carry offline maps if you head inland.
Which is the best eSIM for Australia?
Airalo is the value default; for heavy use on long coastal drives, buy a larger plan.
