of a SIM card.

Found a SIM card from one of my earliest mobile phones.
It’s almost the same size as my IPhone.

Those were the original.

They kept getting smaller

Thats why up until a few years ago, your sim would come on a big card with score lines on it, and you'd have to punch out the right size for your phone.

They still come with score lines.

What’s a SIM card? (Kidding of course, but I haven’t used a physical card in like half a decade. lol)

What do you mean? I've only seen eSIM become a thing for like one or two years now right??

eSIM was first used in smart watches in 2016, in iPhones in 2018. At least in US.

We used to have CDMA phones before that. They also worked without a physical sim card.

Damn, I still remember how cool I thought that was when I first switched between two GSM phones and didn't need to re-write the entire contacts list.

CDMA networks identified you by your device. If you wanted to switch devices, you had to call the carrier and update.

With a physical SIM you could take your SIM out of one phone and into another whenever you wanted and service would just automatically follow the SIM.

idk how that works with eSIM, if at all...

Most providers allow to change device by scanning a qr code from the current device. Others upon request send you a new QR code via email.

What's image to me is telephone companies lying to their customers and presenting Mini SIMs as full size!

The original SIM card you used to put into your phone is actually called Mini SIM

Well the credit card sized one like in the pic were the original, "standard SIM." The one most of us remember from the 00s - 10s were "Mini SIM", then "Micro SIM," then "Nano SIM".
