After purchase, you’ll receive a QR code. Scan it, and your eSIM will activate within seconds. It’s ideal for travelers landing at London Heathrow, Manchester, or Edinburgh Airport who need instant internet access.

Most modern smartphones support eSIM, including iPhone XS and newer, Samsung Galaxy S20+, and Google Pixel 4+. Always make sure your phone is unlocked and supports eSIM functionality.
No. Your eSIM connects directly to local UK carriers, which means you’ll enjoy high-speed local data without any roaming fees. Perfect for short-term visitors, students, and digital nomads.
Most UK eSIM plans are data-only, but you can use WhatsApp, FaceTime, Telegram, or Skype for calls and messages. If you need a local UK number, you can use virtual number apps or VoIP services.
Yes, WhatsApp, FaceTime, and other video/voice calls work normally over mobile data when using an eSIM in the United Kingdom.
The UK does not impose any restrictions or throttling on these popular communication apps, so you can freely connect with family and friends using your favorite services. Your eSIM provides reliable data connectivity, allowing you to make and receive calls, send messages, and use all your apps just as you would at home. This means you can easily stay in touch, share your travel experiences, and conduct video meetings without any issues.

The exact network partner may vary depending on your specific plan.

No! This is the #1 roaming trap. Since Brexit, the UK is NOT part of the EU's "Roam Like at Home" (RLAH) policy. Most EU carriers (like Orange FR, T-Mobile DE, Movistar ES) will now charge you expensive international roaming fees. A Cellesim eSIM is the only way to get a fixed, cheap data price and avoid a massive shock bill.
This specific plan is valid only within the UK. This is a critical point. If you take the Eurostar train to Paris or a ferry/flight to Dublin (Ireland), your connection will stop at the border. For a seamless multi-country trip, we highly recommend our Europe Regional eSIM, which covers the UK, France, Ireland, and all of Europe with one plan.
Yes, absolutely. Our eSIM plan covers all four nations of the United Kingdom: England, Scotland, Wales, and Northern Ireland. You will have a strong 4G/5G signal for using Google Maps in the Scottish Highlands, hiking in Snowdonia (Wales), or visiting Belfast (Northern Ireland).
To give you the best speed and coverage, our eSIM connects to the UK’s premium Tier-1 networks, typically EE, O2, or Vodafone. This ensures you get the fastest available 5G/LTE speeds, whether you are on the London Underground (Tube) or in Edinburgh.
