Apple

My Grandad is in his 70s and up until now, has been pretty anti technology. This will be his first smartphone, and has never really used a "dumb" mobile either.

My Grandma is in and out of hospital at the moment and they're constantly being reminded the world has become digital. He's finally bit the bullet and asked for a smartphone. By the sounds of it, he's actually quite excited, so I'm keeping my fingers crossed that he won't just shove it in the drawer when frustrated.

I've chosen an iPhone XS for him, as I thought it's something that will last a few years but not too fancy. It's got a new battery/screen, I will set up his email, Apple ID and will program in family members numbers. Also, warn him about scams, to not trust anyone who randomly contacts him and to contact me with any concerns.

That being said, I'm hoping to get some advice on:

TLDR:

What might be useful on iOS for an elderly person with no real technology experience?

Any similar experiences you've had that have transferable advice?

Thanks!
