Internet in the UK: everything you need to know
The United Kingdom shows an internet penetration above 96% and one of the best mobile footprints in Europe (source: ITU DataHub, 2024). 4G LTE covers the entire British territory and 5G is broadly deployed in every major city. A UK eSIM is particularly relevant since Brexit, because EU plans no longer systematically include free roaming to the UK.
- ●4G/5G coverage across every major city (London, Manchester, Edinburgh, Birmingham, Glasgow) and tourist hotspots (Cornwall, Lake District, Highlands).
- ●Average mobile download speeds around 75 to 95 Mbps per Ookla (Q1 2025).
- ●Since Brexit (2020), many EU operators have reinstated UK roaming charges: a dedicated eSIM sidesteps that.
- ●Perfect for Citymapper, Google Maps, Uber, Bolt, TfL Go (London transport) and contactless payment apps.

Frequently asked questions
Do eSIMs really work in the UK?
Yes. The vast majority of international eSIMs connect to EE, O2 or Vodafone UK the moment you land at Heathrow, Gatwick or Edinburgh.
Does my EU plan work in the UK after Brexit?
It depends on your carrier. Some retain free UK roaming, many others have reinstated charges. Check with your operator before departure.
Do I need a VPN in the UK?
No. All Western services work normally.
What's the best eSIM for London?
London has full 5G coverage. For a short trip (≤ 7 days) a 3 to 5 GB plan is enough. For 2 weeks with heavy use of maps and transit, target 10 GB.
Do eSIMs work in the London Underground?
Yes on most modernised lines (Elizabeth Line, Jubilee, Central, Northern), with a gradual rollout across the rest of the Tube network.
Can I share my connection with other devices?
Most UK eSIM plans allow hotspot tethering. The detail appears on each plan page on Datadopt.
