Staying connected in a very big country
In Australia the plan uses the Optus network. In big cities such as Sydney, Melbourne, Brisbane and Perth, and in coastal population centres, the connection works well for maps, ride apps and video calls. The country is vast, and in the interior, the desert and on long stretches of road coverage is weak or missing altogether. Optus covers less of the remote areas than the country's widest network, so download offline maps before you set off for the Outback or the more remote parts of the Great Ocean Road.
Out on the water on Great Barrier Reef cruises and boats there is usually no network, and on the islands it varies. In cities hotel wifi is often slow or capped, so your own data is more practical.
A local SIM is sold at airports and in shops, but it has to be registered with ID, in practice a passport. That takes time in queues and activation. You install the eSIM at home and the data starts on landing. Your own number stays in the phone, and WhatsApp calls run over data.

FAQ: Australia
Does the internet work in the Outback and the Australian interior?
Coverage is weak or missing in remote areas, and this plan's network is narrower there. Download offline maps first.
Is an eSIM or an airport SIM better in Australia?
An eSIM is installed at home and starts on landing. An airport SIM needs ID, a queue and activation.
Is the Australia plan valid in New Zealand too?
No, the plan works only in Australia. For New Zealand you need that country's own plan.
What can I use this eSIM for?
The plan is meant for mobile internet on your trip, for example maps, messages and browsing.
Will my own number still work?
Yes. Your own number and SIM card stay active for calls and messages. Choose the Reissaa eSIM for mobile data.
When should I buy the plan?
Buy and install the eSIM before you leave, while you have a stable internet connection.
Will my own mobile plan work in Australia?
EU roaming rules do not apply in Australia, and data on your own plan can be expensive. With an eSIM you know the price in advance.
