Common Questions

The details worth knowing about your Australia eSIM

This eSIM is for Australia only. It does not cover New Zealand or any other country. If you cross the Tasman Sea, you will need a separate eSIM or plan for New Zealand.

Yes, you may. B28 is widely used by Telstra and Optus for rural LTE coverage. Without it, you could lose signal in remote areas. Urban and coastal regions should still work on other bands like B1, B3 or B5.

Your eSIM connects to the Telstra network. Telstra provides 4G on bands B1, B3, B5, B7, B8, B26 and B28, and 5G on n1, n3, n5, n7, n8, n28, n40, n78 and n258.

No. Telstra shut down its 3G network in June 2024, Optus in October 2024, and Vodafone AU in December 2023. Only 4G and 5G are available across all three operators.

Not everywhere. Remote outback regions have no service from any carrier. Telstra has the widest rural coverage, but even it cannot reach all areas. Check coverage maps before traveling to very remote locations.
