The best eSIM for Scotland is a UK eSIM. Scotland is part of the United Kingdom, so any plan that covers the UK works there, from Edinburgh and Glasgow to the Highlands and the islands. Pick a UK data plan that matches the length of your trip. If you're also visiting Ireland, or you need a phone number, choose a Europe plan instead. Below you'll find which plan fits which trip, what signal to expect in remote areas and on ferries, and how to set it all up.
Short on time? These UK eSIMs are data only and work everywhere in Scotland. Pick the one that matches your trip.

What is the best eSIM for Scotland?
There is no separate "Scotland only" network or plan. You use a UK eSIM, and it works in Scotland, England, Wales and Northern Ireland. Start with where you're going, then pick your data and days.
A city break in Edinburgh or Glasgow: United Kingdom 5GB or 10GB
For maps, messages, train tickets and some social media over a week, 5 GB or 10 GB for 7 days is usually enough. If you run low, you can top up the UK plans.
Two weeks in the Highlands and islands: United Kingdom 20GB
20 GB for 15 days covers a road trip from Edinburgh to Inverness, Skye and back, with room for navigation, photos and a few video calls when you have signal.
A month or longer: United Kingdom 50GB, 60GB or 100GB
Staying longer, studying in Scotland or working remotely? 50 GB lasts 30 days, 60 GB lasts 90 days and 100 GB lasts 180 days.
Scotland and Ireland, or more of Europe: a Europe plan
The UK plans only work in the UK. The Republic of Ireland is a separate country, so if you're going on to Dublin or anywhere else in Ireland, pick a plan that lists both the United Kingdom and Ireland. The Europe data plans and the Bouygues Telecom plans do. See all of them on our Europe eSIM page.
You need a phone number: Travel Basic+ or My European eSIM
The UK plans are data only. If a B&B, a tour operator or a car hire desk needs to call or text you, Travel Basic+ from Bouygues Telecom gives you a French +33 number with calls and texts. It also covers Ireland and the rest of Europe, so it suits a Scotland and Ireland trip of up to 15 days. Longer stays? Look at My European eSIM on our Scotland eSIM page. More details: Europe eSIM with a phone number.

Does an eSIM work in the Highlands and islands?
Yes, but don't expect signal everywhere. An eSIM uses the same mobile networks as a physical SIM, so your signal depends on the network and on where you are, not on the eSIM itself.
Scotland has the weakest mobile coverage of the UK's four nations, but it's improving fast. The UK government says 4G coverage from at least one network in Scotland rose from 80% of the land in 2019 to 90% in 2026, and coverage from all networks rose from 41% to 71% (GOV.UK: Rural Scots get mobile signal boost). Recent new masts include sites on Skye, Mull, Arran, Islay and Jura, and on the Ardnamurchan peninsula.
In practice, towns, villages and main roads usually have 4G or 5G. Signal gets patchy in deep glens, on single-track roads in the far north and west, on mountains and out at sea.
Check the coverage on your route
Every UK network has its own coverage map. Look up the places you'll stay, especially if you're heading to the far north, the Outer Hebrides, Orkney or Shetland:
Before you head into remote areas
- Download offline maps while you have Wi-Fi or signal. Google Maps and Apple Maps both let you save an area to use without data (Google Maps Help: Download areas and navigate offline, Apple: Download maps to use offline on your iPhone).
- Save your bookings, ferry tickets and hotel addresses as screenshots or in your wallet app.
- Tell someone your plan if you're hiking, and carry a charged power bank.
- In an emergency, call 999 and ask for Police, then Mountain Rescue (Scottish Mountain Rescue: What happens on a call out?).
On the ferries
Mobile signal on a ferry depends on how far you are from the coast. On short crossings you'll often keep signal most of the way. On longer crossings, like the routes to the Outer Hebrides, expect gaps.
CalMac, which runs ferries to many of the west coast islands, offers Wi-Fi in its port buildings, car lanes and passenger areas on board. It warns that speeds vary and that some sailings have known coverage gaps (CalMac: Wi-Fi). So download what you need before you board.
Where you'll use your eSIM in Scotland
Here is what to expect in the places most visitors go.
Edinburgh
Scotland's capital is compact and well covered. You'll use data for maps around the Old Town, for Edinburgh Castle and museum tickets, and for buses and trams.
Glasgow
Scotland's largest city is well covered too. Use your eSIM for the Subway, train tickets and finding your way between the Riverside Museum and Kelvingrove Art Gallery and Museum.
Loch Ness and Inverness
Inverness is the main hub for the Highlands. If you're staying in a remote spot along Loch Ness, check the coverage maps above before you book.
Cairngorms National Park
The Cairngorms is the UK's largest national park (Cairngorms National Park Authority). Expect signal around the towns and villages, but don't count on it on the high plateau or in the remote glens.
Fort William, Glencoe and the Jacobite steam train
Fort William sits below Ben Nevis, the UK's highest mountain. It's also the start of the Jacobite steam train to Mallaig, which crosses the Glenfinnan Viaduct (West Coast Railways: The Jacobite). Glencoe and the line to Mallaig pass through mountains where signal comes and goes.
Isle of Skye and the islands
Skye is one of the islands with recent mast upgrades. Still, on hikes like the Quiraing or the Old Man of Storr, and on the smaller islands, keep offline maps ready in case you lose signal.
How to set up your eSIM for Scotland
- Check your phone. It must support eSIM and be unlocked. See how to check eSIM compatibility.
- Buy your plan. Your QR code comes by email.
- Install it on Wi-Fi before you fly. It activates on its own when you arrive in a covered country. Step by step: how to install an eSIM.
- Label the line "UK" or "Travel" so you can tell it apart from your home line.
- When you land, make the travel eSIM your data line and turn on data roaming for it. Turn off data roaming on your home line. See the correct roaming settings for an eSIM.
Your home SIM can stay on your phone next to the eSIM, so you still get texts and security codes on your usual number (Apple: Using Dual SIM with an eSIM). Calls and texts on your home line can still cost roaming fees, so check with your carrier. For calls home, WhatsApp or FaceTime work over the eSIM's data.
