a tech illiterate old friend of mine in his 60s got tasked with changing his simcard for new one. But the network just didn't appear. Long story short after 3 hrs of headbashing I asked him to send me the photo of simcard itself
that was a valuable afternoon for my humility

I used to work at a phone repair shop. The amount of people that put Sim cards in their brand new phone without the tray. We would have to take the phones apart to get their Sim cards out.
Isn't the "standard" sim card in you pic actually mini-sim? While the standard one is credit card-sized? I think I have a phone somewhere that takes a credit card sized sim actually.
