For heavy video or hotspot use, step up to the next tier to avoid mid-trip top-ups. At 21 GB+, the Australia matrix unlimited rate is $3.51/day and may cost less than fixed data. HelloRoam unlimited starts from $5; Holafly unlimited starts from $2.99/day.

You can switch during a Australia stay by buying and installing a new eSIM on WiFi. iPhone 13+ holds multiple profiles so the new one can sit beside the old; older iPhones often must delete first. Android varies by maker. Refund windows are HelloRoam 180 days, Holafly 180 days, Saily 30 days, Nomad 30 days, Airalo 14 days; unused data on the old plan may qualify. HelloRoam and Holafly both publish 180 days. The switch takes 5-10 minutes. HelloRoam, Airalo, Holafly, Saily, and Nomad use the same 5G radio, so a switch rarely changes speed.
Can I transfer my Australia eSIM to a new phone?
eSIM transfer between devices depends on the provider, not on Australia. HelloRoam, Airalo, Holafly, Saily, and Nomad each bind a QR to one install in most cases. Airalo can re-download an unactivated profile on a new device. HelloRoam support runs live chat, WhatsApp, and email if you need a replacement QR before activation. Holafly, Saily, and Nomad generally allow one installation per purchase; contact support before activating on the new handset. Apple's eSIM Transfer (cable or iCloud) does not move third-party travel profiles. Install the Australia eSIM on the final phone before a factory reset or trade-in.
