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.
- 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 Australia & New Zealand?
Yes. Your Australia & New Zealand eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. 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 Australia & New Zealand?
Yes, where it has been deployed. 5G runs on The local networks we use in Australia & New Zealand, 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.
Is there phone signal at Milford Sound?
Very little. The Department of Conservation describes mobile coverage on the Milford Road as limited, and you should expect to be offline for most of the drive from Te Anau and at the sound itself, apart from wifi at some terminals. There is no fuel on the road either. Save cruise bookings and offline maps before leaving Te Anau or Queenstown.
Which network does the eSIM use in New Zealand, and is it any good?
It uses Spark. In Opensignal's October 2025 New Zealand report, Spark won Coverage Experience outright with 9.1 out of 10 and tied for first on Availability. One NZ was faster on average download speed. Coverage is strong in cities, towns and on main highways, with gaps in Fiordland, the West Coast and alpine passes.
Will an older phone still work now 3G is switched off in Australia and New Zealand?
It needs 4G. Australia finished switching off 3G in late 2024 and New Zealand's three operators finished closing theirs in early 2026. Phones that rely on 3G will not get data in either country, and Australian networks also block handsets that cannot make 000 calls over 4G. Check older or imported phones on isthisphoneblocked.net.au.
Do I get coverage driving to Uluru or across the Nullarbor?
Only near towns and roadhouses. The plan uses Optus, whose network covers about 1.2 million square kilometres of Australia, so on long outback routes such as the Stuart Highway, the drive to Uluru or the Nullarbor you will have long stretches with no signal. Download offline maps and fill up at every stop.
How much data do I need for 7 days in Australia & New Zealand?
For 7 days in Australia & New Zealand, Viasimo sells 1 GB for $3.00 and unlimited data for $27.99. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Australia & New Zealand: what to know before you land
This plan covers a trans-Tasman trip on one eSIM: Optus in Australia and Spark in New Zealand. Both work well in cities, coastal towns and along the main highways, and Spark topped Opensignal's 2025 New Zealand coverage ranking. Expect long dead zones on outback drives, on the Milford Road in Fiordland and on remote walking tracks.

Fiordland and the Milford Road: planning for no signal
The drive from Te Anau to Milford Sound on State Highway 94 is one of the best-known trips in New Zealand, and the Department of Conservation's own Milford Highway brochure warns that mobile coverage along it is limited. There is also no fuel between Te Anau and Milford Sound. Once you pass the last stretch of coverage near Te Anau, assume you will be offline until you return, apart from wifi at some cruise terminals and lodges.
That has practical effects. Book your cruise in advance and save the confirmation as a file or screenshot. Check road status before leaving Te Anau or Queenstown, because the road can close for avalanche risk in winter and spring. Download offline Google Maps for Fiordland, and if you are walking the Milford, Kepler or Routeburn Track, carry a personal locator beacon rather than relying on your phone.
Other well-known South Island gaps include parts of the Haast Pass, the West Coast between Haast and Fox Glacier, and Arthur's Pass. The North Island's Tongariro Alpine Crossing has patchy coverage depending on where you are on the track.
Optus on the outback and Great Barrier Reef routes
In Australia the plan connects to Optus, which covers almost the entire population but a smaller area than Telstra. On most east coast trips, from Sydney up to Brisbane, Byron Bay, the Gold Coast and Cairns, you will barely notice. The difference appears in remote regions.
Routes where you should expect long gaps include the Stuart Highway between Alice Springs and Darwin, the drive to Uluru and Kings Canyon, the Nullarbor Plain, the Gibb River Road in the Kimberley, and Cape York. Roadhouses and towns usually have signal; the hundreds of kilometres between them often do not. Fill up and download what you need at each stop.
On the Great Barrier Reef, day boats from Cairns, Port Douglas or Airlie Beach lose land signal as they head out to the outer reef, and island resorts vary. Plan to send photos and messages when you are back near the coast. Tasmania's Cradle Mountain and the Overland Track also have very limited coverage.
Crossing the Tasman and the Cook Strait ferry
Most people hop between the two countries on a short flight, for example Sydney to Queenstown, Melbourne to Christchurch or Brisbane to Auckland. When you land, your phone needs to drop Optus and attach to Spark, which usually takes a minute or two. If you are on a cruise that sails between Sydney and New Zealand ports such as Auckland, the Bay of Islands, Wellington or Dunedin, the eSIM only connects when the ship is close enough to pick up a land network; during the two or three days at sea you will be offline unless you buy the ship's wifi.
Within New Zealand, the Interislander and Bluebridge ferries between Wellington and Picton take around three and a half hours, crossing the Cook Strait and the Marlborough Sounds. Expect signal near both ports but gaps during parts of the crossing. Download your ferry booking and onward directions before you board, especially if you are picking up a rental car in Picton.

Twelve days across the Tasman: Sydney, the Blue Mountains, Melbourne and New Zealand's South Island
A first trans-Tasman trip that pairs Sydney and Melbourne with a self-drive loop through the South Island, flying from Melbourne to Queenstown, then on to Milford Sound, Wanaka, Aoraki/Mount Cook and Lake Tekapo before ending in Christchurch.
When to go December to March brings the warmest weather and longest days on both sides, with the busiest roads around Queenstown; October to November and March to April are quieter, while winter (June to August) brings snow to the South Island's passes and road closures on the Milford Road.
-
Day 1 Sydney
Sydney: the Opera House and the Rocks
Start at Circular Quay and walk round to the Sydney Opera House, joining a tour inside if you have booked one. Walk through the Royal Botanic Garden to Mrs Macquarie's Chair for the harbour view, then explore the Rocks and walk across the Sydney Harbour Bridge for sunset from the north side.
Signal Strong 4G and 5G on Optus across central Sydney and on the harbour ferries.
-
Day 2 Sydney
Sydney: Bondi to Coogee and the Manly ferry

-
Day 3 Sydney
The Blue Mountains
Train from Sydney Central to Katoomba, about 2 hours.
Take the train from Central to Katoomba. Walk to Echo Point for the Three Sisters, then follow the Prince Henry Cliff Walk or descend the Giant Stairway into the Jamison Valley. The Scenic World railway and cableway are a quicker way down and up. Return to Sydney in the evening.
Signal Good in Katoomba and at Echo Point; weak or none in the valley floor and on the deeper bush tracks.
-
Day 4 Melbourne
Melbourne: laneways and the Yarra
Flight Sydney to Melbourne, about 1.5 hours.
Fly to Melbourne. Explore the city's laneways around Degraves Street and Hosier Lane's street art, then visit Federation Square and the Ian Potter Centre. In the late afternoon, walk along the Yarra to the Royal Botanic Gardens or take the free city-centre tram to Queen Victoria Market.
Signal Strong coverage across central Melbourne and on the trams.
-
Day 5 Melbourne
The Great Ocean Road
About 4 hours each way by road from Melbourne to the Twelve Apostles.
Join a full-day tour or drive west along the Great Ocean Road past Torquay, Lorne and Apollo Bay to the Twelve Apostles in Port Campbell National Park. Stop at Loch Ard Gorge and look for koalas at Kennett River. It is a long day, so start early.
Signal Good in the coastal towns, but patchy through the Otway Ranges and on stretches between Apollo Bay and Port Campbell. Download an offline map.
-
Day 6 Queenstown
Fly to Queenstown
Flight Melbourne to Queenstown, about 3 hours 20 minutes.
Fly across the Tasman to Queenstown, completing your New Zealand Traveller Declaration and NZeTA beforehand. Collect a hire car if you are driving. In the afternoon, ride the Skyline Gondola up Bob's Peak for the view over Lake Wakatipu and the Remarkables, then walk the lakefront.
Signal Your phone switches from Optus to Spark on landing; it can take a few minutes. Good 4G and 5G in Queenstown.
-
Day 7 Queenstown
Milford Sound
About 4 hours each way from Queenstown by road, or a scenic flight.
Take a coach tour or drive via Te Anau along the Milford Road through the Eglinton Valley and the Homer Tunnel to Milford Sound. Take a boat cruise past Mitre Peak and the waterfalls to the Tasman Sea. If driving, refuel in Te Anau, as there is no fuel beyond it.
Signal Spark covers Te Anau, but beyond it the Milford Road has no mobile signal, and Milford Sound itself has little or none. Tell someone your plans and download offline maps.
-
Day 8 Queenstown
Glenorchy and Arrowtown
Drive the lakeside road to Glenorchy at the head of Lake Wakatipu and walk part of the Glenorchy Lagoon track or the start of the Routeburn. In the afternoon, visit Arrowtown, a gold-rush town with a restored Chinese miners' settlement, and walk along the Arrow River.
Signal Good to Glenorchy town; patchy along the lake road and none on the Routeburn Track beyond the start.
-
Day 9 Wanaka
Over the Crown Range to Wanaka
About 1 hour by road from Queenstown.
Drive the Crown Range Road, one of New Zealand's highest sealed roads, to Wanaka. Walk up Mount Iron for the view over the lake, or start early for Roys Peak if you are fit and the track is open. Visit the lone willow tree on the lakefront at sunset.
Signal Gaps over the Crown Range summit; good in Wanaka and on the lower half of Roys Peak.
-
Day 10 Aoraki/Mount Cook Village
Aoraki/Mount Cook and the Hooker Valley
About 2.5 to 3 hours by road from Wanaka.

Signal Little or none on the Lindis Pass and patchy along Lake Pukaki. Mount Cook Village has limited coverage; the Hooker Valley track has almost none.
-
Day 11 Lake Tekapo
Lake Tekapo
About 1 hour by road from Mount Cook Village.
Drive to Lake Tekapo and visit the Church of the Good Shepherd on the lakeshore. Walk or drive up Mount John for the view over the turquoise lake, and soak in the hot pools in the afternoon. The area is part of a dark-sky reserve, so join a stargazing tour after dark.
Signal Good 4G in Tekapo township; weaker on Mount John's walking tracks.
-
Day 12 Christchurch
Christchurch
About 3 hours by road from Lake Tekapo.
Drive across the Canterbury Plains to Christchurch. Walk through the Botanic Gardens and along the Avon River, where punts run in summer, then see the rebuilt city centre, the Transitional Cardboard Cathedral and the Quake City museum on the 2011 earthquake. Fly home from Christchurch Airport, about 20 minutes from the centre.
Signal Good along State Highway 1 and across Christchurch.
Staying connected on this route
