This is the best part... A fantastic app. I had no problems during my week-long vacation in Paris, France. I used it on my Android phone and the setup was very easy with the QR code. The package prices are also much more economical compared to other e-service providers. Plus, you don't easily use up your internet data unless you're watching videos.
