Day 1 (and 2-3 partially)
When you're prepared for side loading and for possibly sketchy APKs, but stick a sim card in an SD card slot and scratch up the card with a paper clip during the extraction, resulting in 2 days of carrier drama before a successful activation of a new sim safely housed in your modern phone.
You promise your mother to not remove it again, but in your heart of hearts you will put it in your obsolete phone child the next day. And in that slot behind the battery.
