When the app was available on the App Store I was able to download it and create an account. I went to Bangkok and tried using it with no success. A few months later it appeared to be functioning so I requested a ride. It told me no service was available in Scottsdale Arizona so I moved the map to Bangkok and tried requesting it there. I still got the same message. I did this every few weeks until the app disappeared from the App Store. That's my experience with it.
