Frequently asked questions
Which eSIM is best for Australia?
Pick the data amount and validity that match your trip. A small plan covers a few days of maps and messaging; choose a larger plan for longer stays or heavy use. You can top up any time.
Can I keep using my number while using an eSIM in Australia?
Yes. Your physical SIM stays in your phone for calls and texts on your usual number, while the eSIM carries your data. Most recent phones support using both at once.
Can I use a hotspot with my eSIM in Australia?
On most phones, yes — you can share your eSIM data over a personal hotspot. Just enable hotspot or tethering in your phone's settings.
When should I activate my eSIM for Australia?
Install the eSIM at home over Wi-Fi before you travel, then turn the data line on when you arrive in Australia. Data is only used once it connects to a local network.
Do I need an eSIM-compatible phone?
Yes — your phone needs to support eSIM and be carrier-unlocked. Most phones from the last few years qualify; look for an 'Add eSIM' option in your settings.
Is this eSIM data-only?
Yes, these plans are data-only. Use internet-based apps like WhatsApp, Viber or FaceTime for calls and messages over the data connection.
