An Iceland eSIM for a rental car is useful for maps and current travel information, but the important setup happens before driving away from the rental desk.
The route, vehicle contacts and first accommodation must already be available if mobile service drops.
NoveSIM provides data where partner coverage exists; it does not include roadside assistance or guarantee road coverage.
Quick answer: Before leaving, test mobile data with Wi-Fi off, download the first route, save rental and accommodation contacts, connect a suitable charger and check official weather and road conditions.

Keep Vehicle and Connection Problems Separate
A data line cannot solve a closure, unsuitable vehicle or roadside incident. Follow rental and official instructions. For a signal gap, keep automatic selection on and use the offline route; do not delete the eSIM.

FAQ
Can I rely on CarPlay or Android Auto without data?
The interface may work, but map content and routing must be downloaded and tested offline first.
Should I configure navigation while driving?
No. Stop safely and follow local rules before changing the phone or route.
Final Recommendation
Leave the rental desk with the phone, route, power and contacts already tested.
Use mobile data for fresh information while keeping driving navigation offline-ready.
Treat vehicle safety and road decisions independently of the connection.
