Frequently asked questions

How much does an eSIM for United Kingdom cost?

United Kingdom eSIM plans from SimKit range from US$0.59 to US$54.60 depending on how much data and how many days you need. The entry plan is 100 MB for 7 days at US$0.59.

Which United Kingdom eSIM plan is the best value?

Per gigabyte, the best value is the 50 GB plan for 30 days at US$33.15, which works out at about US$0.66 per GB. A plan you only half use is not a bargain, though, so size it to your trip. Every plan here supports top-ups, so it is safe to start smaller and add data if you run low.

Which networks do United Kingdom eSIMs use?

SimKit United Kingdom eSIMs connect to EE and 3, with 5G available where the network supports it. You get the same coverage as a local SIM without swapping anything physical.

Can I use one eSIM for United Kingdom and other countries on the same trip?

Yes. The Europe (41 countries) eSIM covers United Kingdom and 40 more destinations on a single plan, switching to a partner network at each border with nothing to reinstall. For United Kingdom alone, the single-country plans on this page are cheaper per GB.

Is the United Kingdom eSIM 5G?

Yes. Where United Kingdom's networks offer 5G, SimKit eSIMs use it, falling back to 4G/LTE elsewhere. Speeds depend on your device and local coverage.

How do I install and activate an eSIM for United Kingdom?

After you buy, open your order on the phone you'll travel with and tap the install button, or scan the QR code from another screen. The eSIM is ready in under two minutes. Activate it when you arrive in United Kingdom.

When should I buy an eSIM for United Kingdom?

Any time before you travel. The plan's validity only starts when the eSIM first connects to a network in United Kingdom, so you can buy as soon as you book, install on Wi-Fi at home, and it activates when you land.

Can I top up my United Kingdom eSIM if I run out of data?

Yes. If you run low, you can add more data to the same eSIM in a couple of taps from your account, right in the browser, without buying a new one or changing your number.

Will the eSIM work in my phone?

Most phones from 2018 onward support eSIM (iPhone XS and later, recent Google Pixel and Samsung Galaxy models) and must be carrier-unlocked. If your phone shows an "Add eSIM" option in settings, you're good.
