Used this eSIM during my UK trip covering London, Oxford and Edinburgh. Setup was very easy by scanning the QR code before departure. As soon as I landed at Heathrow and turned off flight mode the connection was already active. Data was stable throughout the trip and I used it constantly for Google Maps, train bookings and WhatsApp calls.

Simple activation. Worked perfectly on the London underground.
