Your Australia eSIM in two questions
Which Australia eSIM plan do I need?
Count your days in Australia, then find the trip below that sounds most like yours.
- A three-day city break in Sydney: 1 GB for 7 days covers light use, which is maps, messages and email each day.
- A fortnight touring Melbourne, Cairns and Perth: 10 GB for 30 days gives you room for social media, music and some video.
- A month-long working stay in Perth: 20 GB for 30 days covers your messages, maps and social media.
- A trip that also takes in New Zealand: the Australia & New Zealand bundle covers both countries on one eSIM, so you won't need a second one for the New Zealand leg.
Most plans can be topped up, and the longest is 50 GB for 180 days.

Travelling further?
These eSIMs cover Australia and more countries on one plan.
Will my eSIM have signal in Australia?
Your eSIM joins Optus and Telstra, and both run 5G, so a 5G phone can use it. Cities and main roads are well covered, but signal thins out in the Outback. Your phone picks between the two networks by itself, so there's no switching to do.
Your data reaches the internet through Singapore, a normal setup for travel eSIMs, and here's what that means for you. On daily plans, speed drops to 384 Kbps once that day's allowance is used, so it's worth knowing before you download anything big.
How much data do you need in Australia?
Light: maps, messages, email (about 0.25 GB a day). Standard: plus social, music, some video (about 0.7 GB a day). Heavy: plus streaming, video calls, hotspot (about 1.8 GB a day).

Which networks does the Australia eSIM use?

Can I top up my Australia eSIM?
Yes. Most Australia plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.
Why does my IP address show another country?
Australia plans route your data through Singapore, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in Australia are not affected.
Does it come with a phone number?
Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.
What if my plans change?
Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.
Can I book an Uber from Sydney Kingsford Smith (SYD)?
Yes, Uber and DiDi both run in Australia, so once you're online at Sydney Kingsford Smith (SYD) you can book a ride to the city or your hotel.
Can I use WhatsApp in Australia?
Yes. WhatsApp and Messenger both work on your eSIM in Australia, so you can keep chatting with family back home from Sydney to Perth without swapping SIMs.
Is there 5G in Australia?
Yes, Australia has 5G on its networks, so a 5G phone can connect where the signal reaches. [See which phones work with an eSIM](/esim-phones) before you fly.
Does an eSIM work in Cairns and on the Gold Coast?
Yes. The same eSIM covers Cairns and the Gold Coast, as well as Sydney, Melbourne and Perth, so you don't need a new one when you move between cities.
Is there one eSIM for Australia and New Zealand?
Yes. Australia & New Zealand is one eSIM for both countries, so a single install works in each with no second SIM. If your route is wider, Oceania also covers Australia.
Can I share my eSIM data as a hotspot in Australia?
Yes, you can share your eSIM data from your phone to a laptop. Hotspot use drains data quickly, so keep an eye on your allowance, especially on a daily plan. [See how to set up hotspot tethering](/help/hotspot-tethering).
