Should I get a physical SIM or eSIM for Australia?
eSIM is usually the better pick for Australia if your phone supports it. Quick check: dial *#06# on your phone — if an EID number shows up, you're eSIM-ready, so install before you fly and skip the airport SIM counter. No EID? Go with RORO's physical SIM instead — same network, same top-up flow.
Note: a carrier-locked phone can't use RORO's eSIM or physical SIM either — it needs to be unlocked first. Full supported-device list is on our eSIM Compatibility Check page.
How do I purchase RORO's eSIM or physical SIM for Australia?
Head to the Australia plan page on the RORO site or app, choose eSIM or physical SIM, pick a data plan, then check out with a card, PayPal, Apple Pay or Google Pay — no ID or local address needed. eSIM orders email you a QR code to install right away; physical SIM orders ship to your address, or can be collected at pickup points where available.
When does the validity period start for my Australia plan?
Not at purchase or install — the validity clock only starts once your RORO SIM connects to a network in Australia. That means you can buy and install days or weeks ahead of your trip with no data wasted; it only counts down once you actually land and go online.
Will a phone I bought locally work with RORO's eSIM in Australia?
Yes — any unlocked phone works with RORO, no carrier-lock issues for visitors.
How do I install and activate my RORO eSIM for Australia?
Buy your Australia plan, scan the QR code from your confirmation email over WiFi — under a minute. Nothing activates until your phone connects to an Australian network, so it's safe to install weeks ahead.
On arrival: Airplane Mode off, Data Roaming on for the RORO line, set as your data SIM.
How good is mobile network coverage in Australia?
Sydney, Melbourne and Brisbane all run strong 4G/5G. Australia is enormous and sparsely populated outside the coast, though, so the Outback and remote interior have real gaps — that's true of every network, not just RORO.
Which RORO data plan should I choose for a trip to Australia?
A city-and-coast itinerary (Sydney, Melbourne, the Great Ocean Road) needs modest data. Add a Red Centre or Kimberley road trip with constant GPS and photo uploads, and a bigger tier or Unlimited day-plan makes more sense — top up mid-trip on the same eSIM if needed.
Note: Unlimited plans include 3GB of high-speed data per 24 hours (from activation, resetting every 24 hours) plus a 500MB/24-hour hotspot-sharing allowance — if you need guaranteed high-speed data or unrestricted hotspot sharing throughout your trip, a Fixed plan is the safer pick.
Can I use RORO when I travel to other countries too?
Yes, but a single-country plan only covers that country — it won't work once you cross the border. For a multi-country trip, buy a separate plan for each destination, choose one of RORO's regional bundles if your countries fall within one, or pick a Global plan for the widest coverage. You can hold multiple RORO eSIMs/physical SIMs at once and switch between them.
In fact, your RORO eSIM or physical SIM works across 190+ countries and regions worldwide — keep it installed after this trip and just top up with a new plan whenever you're heading somewhere else, no reinstall needed. A RORO SIM only expires after 2 years with no activity, and every top-up extends that validity by another 2 years.
Does my RORO eSIM or physical SIM expire?
Yes, but only after 2 years of no activity. A RORO eSIM or physical SIM doesn't expire the moment a data plan runs out or its validity period ends — it stays in your phone, ready to top up for your next trip.
Every time you top up with a new data plan, that 2-year countdown resets, so if you travel with RORO regularly the SIM effectively never expires. Only go 2 full years without a single top-up and the SIM itself expires.
What's the difference between RORO's Fixed and Unlimited data plans?
Fixed plans give you a set amount of GB for your whole trip — a small pack is usually enough for maps, messaging and light browsing, and you can always top up if you run low. Unlimited plans are priced by day instead of data volume, but include 3GB of high-speed data per 24 hours (counted from activation and resetting every 24 hours) plus a 500MB/24-hour hotspot-sharing allowance — better if you stream or video call within those limits.
A single eSIM or physical SIM can hold multiple data plans, but only one is active at a time, in the order they expire — plans don't run side by side on the same SIM.
If you want an Unlimited plan but worry about hitting its 3GB high-speed cap, buy a separate Fixed plan on a second RORO eSIM: with both installed, switch to the Fixed-plan SIM once Unlimited's daily high-speed data runs out, then switch back after it resets. And if you plan to hotspot data to other devices or friends, a Fixed plan is the better pick, since Unlimited plans cap hotspot sharing at 500MB every 24 hours.
Do I need to show ID or a local address to buy a RORO eSIM for Australia?
No — just an email address. Skips the ID checks that come with buying a local prepaid SIM at a convenience store.
Can I keep my home number active while using RORO in Australia?
Yes. RORO runs as a second, data-only line next to your existing SIM — home number stays live for calls and texts, RORO handles data, no data roaming charges from home.
What happens if I run out of data in Australia — how do I top up?
Add a pack from the RORO app or site — it lands on your existing eSIM instantly, no new QR code. Top up before you're at zero, since you'll need WiFi to buy more once data runs out — not a given on a remote highway.
To top up: pick a data plan and hit Top Up, then enter the ICCID and PIN of the SIM you're adding it to — or start from your ICCID, choose which one to top up, then pick the plan. Either way, once payment goes through, the new data plan is added straight to that ICCID.
Will I need data for getting around Australia — taxis, buses, trains?
Yes. Uber and DiDi both operate widely in Australian cities, with Ola in some markets too — all need a live connection to book or track a ride, so keep your RORO data on once you're out and about.
Can I book hotels and activities with my RORO data in Australia?
Yes. Booking.com and Expedia are the most-used platforms locally for hotels and tours, alongside the usual global names — either works fine over RORO data.
What payment methods does RORO accept, and how do people pay for things in Australia?
Checkout takes Visa, Mastercard, UnionPay, PayPal, Apple Pay or Google Pay.
On the ground, tap-to-pay is the default nearly everywhere in Australia, right down to market stalls — cash is rarely needed.
What's the emergency number in Australia?
000 (police, medical and fire). Save this before you land.
Emergency calls typically go through on any available network even without an active data SIM, but it's worth having RORO's data running for maps and messaging so you can describe your location clearly if needed.
Does the RORO eSIM support personal hotspot in Australia?
Yes — hotspot to a laptop or a travel companion's phone with no extra setup. Speeds follow local coverage, so it's fastest in the big coastal cities.
Keep in mind the hotspot allowance depends on your plan: Fixed plans share their full data pool with no extra hotspot limit, while Unlimited plans cap hotspot sharing at 500MB every 24 hours.
Anything else worth knowing about using your phone in Australia?
Planning to self-drive the Outback, the Nullarbor or remote parts of WA? Download offline maps and tell someone your route — coverage can vanish for hundreds of kilometers at a stretch, true of every carrier out there, not just RORO.
