The UK has four major networks — EE, Vodafone, O2, and Three — and for tourists sticking to London, any of them work fine. But if you're heading to the Scottish Highlands, rural Wales, the Lake District, or driving through the Cotswolds, the network choice matters a great deal.
The Four UK Networks — Tourist Summary
| Network | London | Rural England | Scotland Highlands | Tourist Verdict |
|---|---|---|---|---|
| EE | ✅ Excellent | ✅ Best rural | ✅ Best in Highlands | 🏆 Best overall |
| Vodafone | ✅ Excellent | ✅ Good | ⚠️ Patchy | Good for England |
| O2 | ✅ Excellent | ⚠️ Moderate | ⚠️ Limited | Cities fine |
| Three | ✅ Good | ⚠️ Limited | ❌ Poor | London/cities only |
Our UK eSIM uses EE — the UK's largest network by coverage area, and the clear choice for any travel outside major cities.
London Coverage
All networks perform well across London. EE and Vodafone have the most consistent Underground coverage (London Tube has WiFi at most stations, and 4G on select lines). Speed in Central London: 30–150 Mbps on any network. For London-only visitors, any eSIM is fine.
Scottish Highlands — Why EE Is the Only Serious Choice
The Highlands is where network differences become dramatic:
| Location | EE | Vodafone | O2/Three |
|---|---|---|---|
| Inverness | ✅ Excellent 4G | ✅ Good | ✅ Good |
| Loch Ness | ✅ Good along loch | ⚠️ Patchy | ❌ Limited |
| Isle of Skye | ✅ Main roads covered | ⚠️ Towns only | ❌ Portree only |
| Glencoe | ✅ Valley floor | ⚠️ Limited | ❌ No signal |
| Ben Nevis area | ✅ Fort William good | ⚠️ Town only | ❌ No signal |
| North Coast 500 | ✅ Partial on route | ❌ Very limited | ❌ Virtually none |
Lake District, Wales, and Cotswolds
| Area | EE | Others |
|---|---|---|
| Lake District (Windermere, Ambleside) | ✅ Towns + main roads | ⚠️ Town centres only |
| Snowdonia / North Wales | ✅ Best available | ⚠️ Limited rural |
| Cotswolds villages | ✅ Good | ⚠️ Variable |
| Peak District | ✅ Good on main routes | ⚠️ Limited off-road |
