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

alt text: nano-simcard rotated 90 degrees forcefully inserted into standard size simcard frame which is missing micro size simcard frame

note the right side of simcard frame bulging out

for confused in terminology
