Older SIM cards were a bit thicker and wouldn’t fit in the newer iPhone trays. Not sure if it’s something you could fix easily.
nanoSIM is thinner, but all the previous generations were the same thickness. You can usually just sand it if it's a problem.
Go look at the ETSI spec for 4FF (nano sim). The +/- tolerances are so large (thanks to 1980s stamping technology) that one can easily manufacture a sim that fits in the overlapping range of both 4FF and older specs - and they do.
I can confirm from personal experience the difference in thickness. With new slide out SIM drawers, if you forget to sand down an old style SIM it can get jammed in forever. Had 2 colleagues who ended up swapping phones after their trimmed SIM got jammed in the wrong iPhone
That sounds like terrible design. I've never had a problem with trimmed SIMs on Nexus phones, without sanding them down.
