I've used the Heathrow Express before and as it was my last trip it was very convenient. Train came quickly and arrived in Paddington without a problem. Wish my flight into Heathrow had been the same!

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

Easy to install and activate. I even installed it at 25000 ft using airline WiFi. Activated upon landing. Seamless fuss free use. My wife was able to link to my phone . All round an excellent product

Aside from the odd drop in signal, due to external factors, this eSIM has been working amazingly and has been our handiest ally with all the walking around in Tokyo.

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.
