Since Brexit, the UK is no longer part of the EU roaming zone. Many European SIM cards that previously included free UK roaming now charge £2–5 per day extra for UK usage. Ovosim's UK plan connects to EE — the UK's largest network — at local rates with no Brexit surcharge. If you're traveling between the UK and Europe on the same trip, use a separate Ovosim plan for each — both install on the same phone and you switch between them at the border.
