Optus eSIM for Australia

Can I get a Optus eSIM for my trip?

You don't need a local contract, an ID check or a shop visit. A JamboSim Australia eSIM connects to Optus's network the moment you land: buy it online, scan the QR once, from $4.50 and with no roaming bills.

About Optus

Optus is a major Australia mobile operator, with strong coverage across cities and popular travel destinations.

When you activate a JamboSim Australia eSIM, your phone connects to Optus (or another supported local network) the moment you arrive, no app install, no manual APN setup. You keep your regular number on WhatsApp and iMessage while data runs on the local network.

Why travellers choose Optus

Nationwide 5G / 4G LTE

Optus operates a modern 5G network across Australia's major cities, with 4G LTE everywhere else.

Instant activation

Buy now, scan once, your Australia eSIM activates automatically when you land.

Travel-friendly coverage

Tested on the routes travellers actually use, airports, hotels, transit hubs and tourist districts.

Auto-connects via JamboSim

Your eSIM picks Optus automatically where available, and falls back to other supported networks seamlessly.

Travelling to Australia from the UK, US or Ireland?

Most UK and US plans treat Australia as a rest-of-world destination, so data outside your bundle is billed per megabyte. A JamboSim eSIM on Optus replaces that with one price you pay before you fly.

Cheaper than your home roaming

EE, Vodafone, O2 and Three, and in the US Verizon, AT&T and T-Mobile, all charge a daily or per-MB rate for Australia. Your Optus data runs on a local plan instead, with no bill shock when you get home.

No local SIM shop, no ID checks

Buying a Optus SIM in Australia usually means a passport copy, a registration form and a queue at the airport. The eSIM is installed before departure and connects on landing.

English support, prices in GBP or USD

You pay in your own currency and our support team answers in English, seven days a week, including install help for Optus.
