Frequently Asked Questions

Everything you need to know about this eSIM plan.

Your Australia eSIM runs on Optus — Australia's leading network for speed and performance, winning the most award categories of any Australian carrier in Opensignal's October 2025 Australia Mobile Network Experience Report including 4G and 5G Download Speed, Video Experience, and Games Experience. Optus covers 98.5% of the Australian population with its 4G and 5G mobile network.
Install your Australia eSIM the evening before your trip begins. Validity starts from installation — not purchase or first data use. Installing at home the night before means your plan is live and ready the moment you land in Australia, with no setup stress at the airport.
Always purchase at least one extra day beyond your planned stay. Australia's time zone offset from GMT+8 means your daily allowance may reset at an unexpected local time — and long-haul return flights from Australia can span more than a calendar day. The extra day ensures you're covered throughout your journey home.
Validity starts from the moment you install the eSIM — not when you purchase it. You can buy well in advance without losing any days. Just hold off on installation until the evening before your departure.
Yes, and we strongly recommend it. Install via QR code at home on Wi-Fi the night before departure. Your connection will be ready the moment you land in Australia — no airport counter visits, no language barriers at arrivals.
Yes, excellently. Optus provides strong 4G and 5G coverage across all of Australia's major cities. Optus averages over 200 Mbps on 5G downloads in metropolitan areas — the fastest of any Australian carrier. Navigation, social media, ride-hailing, and booking apps all run at peak performance throughout Australia's cities.
This is where honest framing matters. Telstra has won Australia's Coverage Experience and 5G Coverage Experience awards for five consecutive reports — meaning Telstra has the widest geographical footprint in rural and remote Australia. Optus covers 98.5% of the Australian population, but Australia's landmass is enormous — the vast majority of the outback, remote national parks, and unpopulated inland areas fall outside all carrier coverage. If your itinerary includes extensive remote driving — the Nullarbor Plain, Cape York, the Kimberley, or deep outback routes — download offline maps thoroughly before departure and consider a satellite-capable device for emergency communication in truly remote areas.
Optus averages 208.4 Mbps on 5G downloads — nearly 20% faster than Telstra and 30% faster than Vodafone — and has held Australia's fastest 5G title for nine consecutive Opensignal reports. On 4G LTE, Optus also leads Australia's Download Speed Experience. For everyday travel tasks in cities and popular destinations, your Australia eSIM delivers the fastest mobile data experience available in the country.
The vast majority of travel and social apps work perfectly — including Google Maps, Uber, WhatsApp, Instagram, Facebook, Messenger, YouTube, Agoda, Booking.com, FaceTime, and more. However, TikTok and most AI-powered applications (including ChatGPT, Gemini, Grok, and similar tools) are not supported due to network-level restrictions on this plan. For those apps, switch to hotel Wi-Fi or your home SIM temporarily.
Yes, both Uber and DiDi work perfectly on your Australia eSIM. Uber operates in Sydney, Melbourne, Brisbane, Perth, Adelaide, and most major Australian cities. DiDi is also widely used across Australian cities as a more affordable alternative, and works perfectly over your data connection.
No — this is a data-only eSIM for Australia. It does not include a local Australian number for voice calls or SMS. For all communication needs, WhatsApp, FaceTime, Messenger, and other VoIP apps work perfectly over your data connection.
