I actually do, it's always good to have a few back up essential things if they don't take up too much space. Every time I go camping/travelling I update my old OnePlus 3T (LineageOS is still up-to-date which is amazing) and bring it with me. If my iPhone breaks I can move the SIM card and still keep at it.
Agreed. Both wife and I need our phones for work connectivity, and it's a lot easier just to carry our old models in case one of ours dies on a trip. I'm not going to buy an iPhone while on a trip out of the country - they won't even have the models that support Verizon in most markets.
My old phone is still logged in to Apple, still works, still holds a charge. I'd like some eSIM system that was as convenient as "phone dies, pull SIM, put in old phone, boot".
