Hand me down's from my son to me is how I have been for many years now, he never bought any Apple products as they are over the top expensive.
Invested into fibre line when that arrived, then purchase data there and separate on phone when away from house connection, or when fibre is down. ZAR1k/m which is an expense on it's own.
I'm not into Apple products either although used to be. I got annoyed that I had to keep putting my apple ID in all the time. I'll never have an Apple phone again.
Researched years ago, Apple if you have the money to integrate full system in phone, laptop etc. it may be viable in a country where it is supported. Not something I would touch with a barge pole, too expensive here.
