United Kingdom eSIM brief
Post-Brexit the UK is outside the EU roaming zone, but most Europe-regional eSIMs still include it commercially — though not all, so always check the country list before buying. London has dense 5G and growing Tube coverage, while the Scottish Highlands and rural Wales remain the weak spots, where EE-based plans hold up best. Ideal for city breaks and anyone combining the UK with mainland Europe.

Three things to know
- Post-Brexit the UK is outside EU roaming, but many 'Europe' eSIMs still include it commercially — coverage is plan-specific (some providers split 'Europe' from 'EU + UK'), so check the country list.
- London has dense 5G and the Underground now has coverage on many central stations, with full Tube coverage still being rolled out.
- The Scottish Highlands and rural Wales are the main weak spots; EE-based plans tend to be the safest bet for rural and remote areas.
- A travel eSIM is a roaming line — turn on Data Roaming for the eSIM after install, or it won't pass data.
