#NearSectionLengthCoords
No continuous dead zones of 2 km or longer were identified.
How this is estimated. Coverage is modelled from OpenCellID crowd-sourced cell-tower locations. A point counts as covered by an operator if it falls within a conservative per-technology range of one of that operator's towers (5G 3 km / 4G 6 km / 3G 5 km / 2G 12 km). This flags stretches where you're likely to lose signal, but it is an estimate from public data—not a field measurement or guarantee. Real signal varies with terrain, weather and network load.

Frequently asked questions

How much data do I need for Great Ocean Road (B100)?

Aim for at least 500 MB a day — comfortable headroom for daily navigation, booking accommodation, messaging home and uploading photos. The featured plan is picked on exactly that rule; size up if you stream, video-call or share your connection.

When do the plan days start counting?

On first use — installing the eSIM and connecting starts the clock, not the purchase date. You can safely buy weeks before your trip.

Does my phone support eSIM?

Most phones released since 2019 support eSIM, including iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy models. Your phone must also be carrier-unlocked.

What if I change my mind after buying?

Uninstalled eSIMs qualify for a full self-service refund within 14 days of purchase — no questions asked. Once the eSIM is installed on a device it can no longer be returned. See the refund policy.
