About this eSIM

Brisbane wraps around its river, all sunny riverwalks and jacaranda streets. Laze on the man-made beach at South Bank, ride the CityCat ferry past the Story Bridge, then climb Mount Coot-tha for the skyline at dusk. Set up your eSIM before you fly in and it's live by the time you clear the airport, with 5G across the CBD, West End and Fortitude Valley. No roaming to think about, so you can plan a Moreton Bay day trip or grab CityCat times whenever you like.

Brisbane keeps you connected best across the CBD, South Bank and the stretch toward Fortitude Valley and West End, plus the CityCat ferries. It can thin out in the leafy outer suburbs and up in the D'Aguilar ranges. Install your eSIM before you fly and switch it on when you land so it registers straightaway, and leave your home number active for calls. Tip: save an offline map before a Moreton Island day trip, where coverage gets patchy.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
The eSIM selects a host network automatically. You cannot pick or switch between them.
Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Brisbane?

Yes. Your Australia eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are Optus. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Brisbane?

Yes, where it has been deployed. 5G runs on Optus in Australia, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

How much data do I need for Brisbane?

These are Viasimo's sizing recommendations, not measurements of your trip. Maps, messaging and the occasional lookup run to roughly 1GB a week. Streaming, video calls or tethering a laptop push that to 3-5GB a week, and uploading photos and video moves past it faster still. The data calculator on this site works it out from how you actually use your phone. Sizing one tier up costs less than topping up part-way through a trip.

Is an eSIM cheaper than roaming in Brisbane?

Usually, though it depends on your own carrier. A roaming day-pass is charged for each day it is active whether you use the data or not, while a prepaid bundle is one up-front purchase for a fixed amount of data. The gap widens on longer trips. Check your carrier's published rate for Brisbane before you fly rather than taking our word for it.

How do I install my eSIM?

After checkout we email you a QR code. On your phone, open Settings, then Cellular or Mobile data, tap Add eSIM, and scan the code. Installation takes under a minute.

When does my Brisbane eSIM activate?

Your plan activates automatically when you arrive and connect to a local network, so your validity period only starts once you land.

Can I keep my regular number?

Yes. The eSIM is data-only and runs alongside your physical SIM, so you keep your home number for calls and texts while using Viasimo for data.

Can I top up or extend my plan?

Yes. You can buy more data or extend your plan at any time from your account before it expires.

Does it support hotspot and tethering?

Tethering is supported on most devices, so you can share your connection with a laptop or other devices.
