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.
Good value eSIM for travelling around the UK. strong signals even on trains between cities and speeds were good enough for streaming and video calls.
Connection stable in Manchester.
