How reliable is eSIM coverage in rural areas of New Zealand, like around Milford Sound or the Catlins?

Question

I'm planning a road trip through the South Island and will be spending a lot of time in remote areas. I need to stay connected for navigation and emergencies, but I'm worried the eSIM might not work where there's no cell tower. Can anyone share their experience with coverage in rural New Zealand?

Sara (GotoeSIM) · Accepted Answer

Our eSIM in New Zealand uses the same major networks as local SIMs, so coverage in rural areas depends on the underlying network. In places like Milford Sound and the Catlins, you'll find coverage in towns but it can be spotty or nonexistent on remote stretches. We recommend downloading offline maps for navigation.

I drove the South Island last year with an eSIM and had signal in most towns, but once you're on the road between them, it's hit or miss. Milford Sound had no signal at all, so be prepared.

The Catlins were particularly patchy for me. I'd get signal at lookout points but lose it quickly. Make sure to download maps and music beforehand.

To add to Sara's point, we always suggest checking the coverage map of the local network provider before you travel. If you're in an emergency, 111 calls will use any available network, even if you don't have a signal for data.

I found that having a backup power bank was crucial because my phone would constantly search for signal in remote areas, draining the battery fast. Also, consider a personal locator beacon if you're going really off-grid.

Surprisingly, I had decent coverage around Milford Sound with my eSIM, but that was because I was close to the visitor centre. Once I started hiking, it dropped. So it really depends on exact location.

For emergencies, it's worth noting that New Zealand's emergency call system works even without a SIM card, so as long as any network is available, you can call 111. But for data, you'll need coverage.

I used an eSIM from another provider and had similar experiences. The key is not to rely solely on it for safety. Tell someone your plans and carry a map.
