Travel eSIM
eSIM for Australia
Australia is a long-haul, long-stay trip for most US travelers, and the distances mean you're often navigating well outside a city. Coverage concentrates along the coasts and major routes and thins out in the interior, so download offline maps before any Outback leg. A travel eSIM keeps you connected for the city stretches without a month of roaming charges.

How eSIM works in Australia
Australia supports eSIM across the market, with travel plans generally routing through Telstra, Optus, or Vodafone Australia.
Buy the plan, scan the QR code the partner emails you, and install the profile while you're still on Wi-Fi. Switch the line on when you land.
How much data do you need?
Longer trips and remote-work stays push data use up; choose a larger or extendable bundle for multi-week itineraries.
Going abroad from the US?
Every S Mobile unlimited phone plan already includes world eSIM data and free calling and texting to 85+ countries — so your everyday plan travels with you before you even add a destination eSIM.
FAQs — travel eSIM in Australia
Will my phone work with an eSIM in Australia?
Most recent iPhone, Google Pixel, and Samsung Galaxy models support eSIM, but your phone also has to be carrier-unlocked. Check your phone's settings for an "Add eSIM" or "Add cellular plan" option before you buy, and confirm device compatibility with the partner at checkout.
How do I set up a travel eSIM before flying in Australia?
Buy from the partner store, then install the eSIM profile while you still have Wi-Fi at home. It stays dormant until you arrive and switch it on, so you land connected without hunting for a SIM counter.

Yes. A travel eSIM adds a data line alongside your existing line, so your US number stays active for calls and texts over Wi-Fi or your regular plan while data runs on the travel eSIM.
Does S Mobile Wireless run the network in Australia?
