    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.

    So far I am enjoying the service. I only find that I am not able to hot-spot my laptop, which is a bummer because it would have been great for me to do this for my email and light Web browsing

    I’m extremely satisfied with the data. Thanks to it, I don’t have to worry about internet access in Asia. I’m currently in the Philippines and the SIM card works great. I can take photos and upload them to Instagram instantly, anything I want and quickly. And the price is unbeatable.

    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

    The only way to travel from the Heathrow Airport! Clean and comforable cars, easy access to the platform. I will use it again if I'm back in London

    Fantastic - very efficient and easy way to get to the city of London without the hassle and expense of a cab. We bought our tickets in advance and were prepared once landed. The Express was no more than a five minute walk from the terminal and once we arrived to Paddington station we took a cab from there to our hotel as we had a few pieces of luggage. I wish every major city around the world had a similar service!
