Iceland eSIM Guide: Ring Road, Highlands and the Northern Lights
Most visitors to Iceland rent a car and drive, whether it's a few days on the Golden Circle and south coast or two weeks around the Ring Road. Coverage along the main roads and in towns is good for such a sparsely populated country. The highlands, the Westfjords and the F-roads are where it thins out, and those are also the places where weather and road information matter most.
Which networks Iceland eSIMs use
Iceland's mobile operators are Síminn, Nova and Vodafone Iceland. Among the wholesale Iceland plans we track:
| Plan type | Networks | Where data exits |
|---|---|---|
| Roaming, two networks | Nova, Síminn (5G) | France, Netherlands or UK |
Two networks give your phone a fallback on remote stretches of road. Data exits in Western Europe, which works fine for maps, road conditions, weather and messaging.
Iceland isn't in the EU, but it's in the European Economic Area, and all three Europe plan families compared in our Europe guide include it. Check the country list anyway if you're combining Iceland with other countries.
Coverage
| Area | What to expect |
|---|---|
| Reykjavík and towns | Strong 4G, with 5G in parts |
| Golden Circle and south coast (Vík, Jökulsárlón) | Good along the road |
| Ring Road (Route 1) | Mostly covered, with gaps in parts of the east and north |
| Westfjords | Patchy between villages |
| Highlands and F-roads (Landmannalaugar, Kjölur) | Limited or none for long stretches |
| Glacier hikes and ice caves | Variable; guides carry their own communications |
Roads, weather and safety
Iceland's weather changes quickly, and roads can close for wind, snow or flooding at short notice. Before setting out each day:
- Check road conditions on the official Icelandic Road and Coastal Administration website, umferdin.is.
- Check the weather forecast from the Icelandic Met Office (vedur.is), including wind warnings.
- Check safety alerts on the official SafeTravel website, safetravel.is, where you can also leave a travel plan.
- Download offline maps for the whole day's route.
F-roads are only open in summer and require a 4x4. Rental agreements often restrict where you can drive, so check yours.
The northern lights
Northern lights forecasts from the Icelandic Met Office show cloud cover and aurora activity. Good viewing spots are usually dark places away from towns, which often means weaker signal. Check the forecast before driving out, and save your route back to your accommodation.
Sharing data on a road trip
On a road trip, one phone usually navigates while the others are passengers. Sharing one eSIM by hotspot works, if the plan allows tethering, and our hotspot guide covers the details. If your group splits up for hikes or tours, separate eSIMs avoid leaving someone without data.
Driving with your phone
Iceland has strict rules on phone use while driving, and roads can be narrow, gravel or icy. Mount your phone and set the route before you leave. Single-lane bridges and blind hills are common on the Ring Road, so keep your eyes on the road rather than the map. If you need to check something, stop in a proper pull-out, not on the roadside, which is a common cause of accidents in Iceland.
How much data you'll need
| Trip | Suggested data |
|---|---|
| 4 days, Reykjavík, Golden Circle and south coast | 3 GB |
| 10 days on the Ring Road | 5 to 8 GB |
| 2 weeks including the Westfjords | 8 to 10 GB, with offline maps |
| Sharing with a travel partner | Add half again |
Guesthouses and hotels nearly always have Wi-Fi. The data guide has per-activity figures.
Setting up and troubleshooting
Install the eSIM at home over Wi-Fi and switch it on after landing at Keflavík. Set it as your cellular data line and enable data roaming for it. If there's no service, toggle airplane mode, then select Síminn or Nova manually. The troubleshooting guide covers the rest.
Emergency calls
The emergency number in Iceland is 112. In areas without mobile coverage, emergency calls may still connect through another network if one is in range, but don't rely on it in the highlands.
Before you fly: a short checklist
- Install the eSIM at home over Wi-Fi and leave it off until you land.
- Save the official road, weather and safety websites to your home screen.
- Download offline maps for Iceland.
- Pack a car charger or power bank; cold weather drains batteries.
FAQ
Do Iceland eSIMs include an Icelandic number?
Most travel eSIMs are data-only. Local prepaid SIMs are available in shops and petrol stations.
Is there signal on the Ring Road?
On most of it, yes. There are gaps in parts of the east and north.
Will my eSIM work in the highlands?
Expect long stretches without signal. Leave a travel plan with SafeTravel and carry offline maps.
Is Iceland included in Europe eSIM plans?
Often, yes. Check the country list, as plans differ.
Can I see the northern lights forecast without data?
No, you need a connection to check it. Look before you leave town for the evening.
