The UK has excellent mobile infrastructure, especially in England. An eSIM gives you fast local data without paying your home carrier's international roaming rates.
Networks in the UK
Four main operators: EE (best coverage nationally, especially in rural Scotland and Wales), Vodafone (strong urban and suburban coverage), O2 (reliable in cities), and Three (competitive pricing, strong urban 5G). Most travel eSIM plans run on EE or Vodafone infrastructure.
Pricing
UK eSIM plans run $1.50–$3 per GB. A 10GB, 30-day plan typically costs $15–$25. Note: since Brexit, UK plans are no longer automatically part of Europe regional plans — check carefully if you're combining a UK visit with EU travel.
Coverage
- London: Excellent 4G/5G on all networks
- Major cities (Manchester, Edinburgh, Birmingham): Strong coverage
- Rural England: Good on EE; patchier on Three
- Scottish Highlands & Islands: EE has the best coverage; others are limited
- Wales & Northern Ireland: Reasonable in towns; rural coverage varies
Tips
- If visiting both the UK and EU, buy separate plans — don't assume a European plan covers the UK
- London's Tube (Underground) now has 4G in most stations
- National Rail coverage is generally good on major routes
