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.
