Travel eSIM in the United Kingdom: connected from touchdown

In the United Kingdom, you are outside the European Union: EU "roam like at home" rules don’t apply, and using your usual plan can be expensive. A travel eSIM is set up at home before you leave and works as soon as you land.

Your three options

A travel eSIM
A virtual SIM bought online: you install it over Wi-Fi before leaving and switch it on when you land. Convenient, no shop to find. Check that the plan covers the country and the length of your stay.
Your own provider’s plan
Some providers offer add-ons for this country: compare their terms before leaving. Without one, roaming outside the European Union can be very expensive.
A local SIM card
Sold at the airport or in shops, often with ID required. Good for a long stay, but you have to swap cards, and therefore numbers, during your trip.

From the moment you arrive in the United Kingdom

With data from touchdown, you can follow your route, call a ride or show your booking. What awaits you on arrival in our cities:

  • London : Eurostar links Paris to St Pancras International in about 2h16. From Heathrow, the Heathrow Express reaches Paddington in about 15 minutes. An Electronic Travel Authorisation (ETA) and a passport are required for EU travellers.

Setting up an eSIM, step by step

  1. Check that your phone supports eSIM and is unlocked (phone settings or the manufacturer’s website).
  2. Buy the eSIM and install it at home, over Wi-Fi, a few days before leaving (a QR code or an in-app installation).
  3. On arrival, switch mobile data and data roaming on for the eSIM line.
  4. Keep your usual SIM active for calls and texts (bank codes), but turn off its mobile data.

At home, over Wi-Fi, a few days before leaving. You then switch it on when you land, simply by changing the line used for data.
