    The ORBITEL 901 was one of the first "mobile" phone to use sim cards:
    But this website says it use the mini-SIM formats.
    The full-size format is the default smart card dimensions. It might not have been used inside a real phone.

  • Beautiful. The full-size one reminds me of the 8" floppy disks of yore. I'd like to see sample pictures of a few devices that used the full-size SIM card.
