You forget how vulnerable you are until your phone stops working. Anyway, most phones seem to come with a pin tool to open the sim card-chip slot. I decided it is a good idea to tape the sim slot tool to the charger brick because I would lose it otherwise, it is so small.
I feel the same way about micro SD cards, they're so small, I feel like a strong breeze could blow it away and it could fall into a crevice that I can't search. I remember when we used to use cassette tapes, they were the perfect size, they were small hand sized plastic cartridges with magnetic tape reels nested inside them. You wouldn't lose those things so easily. They mostly stored music but there was a time when they also were used to store computer data.
