Technology, love it or hate it, we need it nowadays!!
My favourite item of technology has to be my Samsung galaxy phone. It is essential for me that I can always contact someone in an emergency, so this is a vital thing for me to have, not a luxury item.
Whilst I do have it for that vital need, it helps with so many other things, emails, keeping in touch with friends, assistance apps, maps, WhatsApp to keep in touch with and send messages/photos/voice messages to friends and family, notes and reminders, calendar, banking, store card apps, taking photos, and writing on here.
I use this app https://passengerassistance.com for train travel, it allows you to set up your own profile and book the assistance you need for the journey. You can find it as an app on your phones app store, or access the website via the link I have provided. I highly recommend it.
