🇬🇧 eSIM for the United Kingdom
Since roaming charges returned for many EU travellers, the UK has quietly become an expensive place to use your home plan. A local data eSIM avoids the per-day surcharges most European carriers reintroduced.

- Coverage is dense in England; the Highlands and parts of Wales are thinner.
- Contactless travel across London needs a working connection for ticketing apps, though bank cards work at the gate.
- A UK plan does not automatically cover Ireland — check a regional plan if you are crossing.
How to get connected

- Scan the QR code the app gives you — Settings → Cellular → Add eSIM.
- Turn on data roaming for the Num line when you land.
Questions about the United Kingdom
How much does an eSIM for the United Kingdom cost?
Plans start at $1.14. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a the United Kingdom eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
