I find using Travelex Cash Passport to be an easy way of charging when traveling. The only problem I had was that I was unable to refill my card using my iPhone. Fortunately I had my laptop with me and that worked seamlessly. A couple of years ago I used the same card and had no problem using my phone to access the website. This time I used the Travelex app, and that is what did not seem to work. Other than that, I am very pleased.
