Why Get an eSIM for Australia?
- Online from the arrivals hall, ready for the train, a ride app, or your rental car.
- Navigate long drives with live maps and fuel stops.
- Keep your number for bank codes and messages from home.
- Avoid expensive roaming with most home carriers.
How to Choose an Australia eSIM
Trip length
Australia trips are often long, two weeks or more. Pick a plan that covers your whole stay plus a spare day. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps and messages use little data. Video calls, streaming, and uploads from the reef use much more. Here is a guide to how much data you need when you travel.
Where you are going
For Australia alone, an Australia eSIM is the best value. If you are combining it with New Zealand or Asia, see the regional option below.

How to Set Up Your Australia eSIM
- Check your phone is eSIM-compatible and carrier-unlocked. See our eSIM compatibility list.
- Buy your plan. The QR code arrives by email within minutes.
- Install it at home on Wi-Fi with our installation guide.
- When you land in Australia, switch the eSIM on, set it for mobile data, and turn on data roaming for that line. Keep data roaming off on your home SIM.
Tips for Staying Connected in Australia
- Expect gaps in the outback. Coverage is strong in cities and towns but disappears on long stretches between them. Download offline maps and tell someone your route.
- Use contactless on public transport in Sydney and Melbourne, or the local transport card.
- Check for bushfire and weather alerts with the official state emergency apps in summer.
- The emergency number is 000. Save it, along with your accommodation details, before a remote drive.
- Need to call? egoViet eSIMs are data-only, so use WhatsApp or FaceTime. Here is how calling works with a data-only eSIM.
