We are waiting for confirmation of the booking. We need the eSIMs for this October, as we are traveling to the UK (London) for a few days.

Very smooth connection, worked perfectly fine in Turkey and Spain, hopefully continues to ease the rest of my trip to Europe.

The eSIM was very easy to install and set up. It was extremely useful for my short trip and saved me the hassle of buying a new physical SIM card. The process was smooth, convenient, and worked well throughout my travel.

Very convenient and reliable service! Buying the tickets online in advance was definitely a smart choice and made everything quick and easy. There were helpful staff members at the gates in case anyone needed assistance. The journey was smooth and stress-free. I would definitely recommend the Heathrow Express to anyone traveling between Heathrow Airport and Paddington.

It was easy to use and not have to deal with auto traffic. Nice to access directly at the Terminal. Good storage area for suitcases and comfortable seats.

Slightly handicapped, but was offered help with luggage and guidance where to find the track for my connection. Service to find gates and facilitated entry, since my first experience from using railway in UK. Aircondition and very fast transport to LHR. Lars

The Heathrow Express is just the simplest, fastest and most comfortable way to travel into London City from Heathrow. There is no comparison, enough said. Try it for yourself. Axel, Sydney Australia
