The main carriers are EE, Vodafone, O2. 5G/4G in England, Scotland, Wales and Northern Ireland, including train routes. Continuing on the Eurostar to Paris? You stay connected.
A travel eSIM like VoaSim uses those same towers: coverage is that of the local networks.
| Option | How it works in practice |
|---|---|
| Travel eSIM | Bought online before the trip, arrives by e-mail and connects on landing. Unlimited from USD 1.79/day at VoaSim, no paperwork or queues. |
| Local SIM | Prepaids from EE, O2, Vodafone or Three cost GBP 10-20 and are sold at supermarkets with little hassle. Note: since Brexit, UK SIMs do NOT include free EU roaming on several plans. |
| Your carrier's roaming | Convenient but with a daily cost that piles up, and passes usually carry few GB or fair use. Check the exact rate in your app before flying. |
| Wi-Fi only | Free, but leaves you without maps, translator or rides on the street — exactly where you need them most. |
London has patchy signal inside the Underground (4G/5G only on some stretches). In rural Scotland and Wales coverage thins out in the Highlands and the parks.
Heathrow and Gatwick have free Wi-Fi (with registration). If you continue to mainland Europe, check your plan covers both sides of the Channel — a multi-country eSIM solves it automatically.
