miniSIM is the "normal" SIM. The step up is just "SIM", which is the size of a credit card. I doubt that's the size of the holder in the pyra.
I had no idea it was called MiniSIM... and that SIM refered to credit-card sized. Glad I learned something
Here is a Wikipedia graphic showing all sizes:
Hmmm... That chip position in the full-size card is quite suspicious. I remember around 1998 seeing someone open a phone to show (what appeared to me to be) a bank debit card in their phone. I assumed that they were charged directly from the card as they used the phone. So, either that person was using a full-sized SIM card instead (though one that was green and looked suspiciously like a Lloyd's Bank card) OR the full-size SIM card was designed to replace debit/credit cards used in phones.
Does anyone recall phones taking debit/credit cards within them, or full-size SIM cards?
The position looks about right to me. I remember seeing full size SIM cards in the 90s. When MiniSIM was introduced, mobile phone providers would provide full size SIM cards that had most of the outline of the MiniSIM drilled out, so if you needed a MiniSIM you just pushed it out of the full sized SIM card and discarded the rest.
