Pick by travel style

🎡 London city breakAny network works — pick the cheapest per-GB tier. Deep Tube platforms are still patchy.

🏰 Scotland & Lake DistrictSignal is sparse in the Highlands — prefer EE-based plans.

🎓 University visits / long staysA 30-day big-data tier beats weekly renewals, and hotspot sharing helps with laptops.

FAQ

Can I use a Europe regional plan in the UK?

Some work but are often capped or throttled; a dedicated UK plan is usually better value — which is exactly why we run a separate UK page.

Do UK eSIMs require ID?

No — buy online, delivered instantly, no verification.

Will it work in Dublin?

Ireland is in the EU; most UK-only plans exclude it. Check coverage before crossing or switch to a regional plan.
