Only Satan would design a hole that is smaller than the end of a bent paperclip when the entire purpose of the hole is to put something into it.
For anyone else who ever has this problem, there are easier ways than a paper clip and hammer.
I have used pencil lead (0.5mm) successfully. You get a short piece and push hard, it might hurt your thumb a bit but it works. Obviously most needles work but I have used things like safety pins from the back of a shirt pin. I’ve also used the tip of mechanical pencils in a pinch. And if you’re crafty you can do something (carefully) with a toothpick and a knife to shave the tip down. Dumbest thing I’ve ever used is a disposable flosser that had a toothpick on the end. I also used that to clean USB C ports. All of these also similarly work on small reset buttons on routers and such.
I guess it’s called a SIM card eject pin tool, but you’ll usually find them in cell phone toolkits.
there must be an everyday item that functions as a makeshift alternative.
