In your place I would purchase the ticket once i landed from a ticket machine though. I don’t count on my phone working in a foreign country.
I'm less worried about my phone than the time spent buying a ticket. I can actually buy the ticket for my upcoming trip today, before I even leave the US.
I guess what was a bit confusing, is the that generally when you buy from a machine you're prompted to enter the type of ticket you want, starting point and ending point and then you validate it on the train.
The the HandyTicket, you buy the ticket from a display of specific times/routes, so the process has an extra step. I'm not sure if that route then displays on the resulting "ticket" on your phone limiting it's validity to that particular combination of time and route,, or it it doesn't matter..
