What actually uses data in Iceland

• Google Maps navigation — ~5MB per hour of driving (much less if you download offline maps first).
• Northern Lights & weather apps (vedur.is, Aurora forecast) — tiny, a few MB/day.
• Messaging & social — WhatsApp/Instagram browsing ~50–150MB/day.
• Photo & video uploads — the big one: 100–500MB if you back up to the cloud daily.
• Streaming music/video — avoid on data; download before you go.

3 ways to make your data last

1. Download offline Google Maps of the Ring Road and Reykjavík before you fly.
2. Turn off auto photo-backup on cellular; let it sync on hotel Wi-Fi.
3. Download Spotify/Netflix offline for long drives.

Running low? Just top up

If you underestimate, you can top up instantly in the Airalo app without buying a new eSIM — so it's safe to start with 3GB and add more only if you need it.
