Starting May 20, I will be traveling around central Italy by train and have pre-purchased some e-tickets. Even though I plan on carrying printed tickets as a backup, I'd like to use the smart phone for holding ticket info, checking in, etc. My previous experience in Europe showed that some of the phone features worked fine (Google Maps, local calls), while others like email mostly didn't. I have loaded the Trentialia app on my phone in hopes it will help, but right now it can't pull up any info. My guess is the service is blocked outside of Europe.
Do most train and metro stations have public wifi, or do I need cell service?
If you don't have a working phone, how do you check-in before boarding?
Does Trenitalia reflect current info on strikes?
