From the picture guide above, you can see that all of these devices use three different SIM cards. These are the type of SIM cards and the compatible devices for them:

  1. 1
    Mini SIM Card -- The mini SIM is the most common type of SIM on the market today
    .
    From the three SIM cards that will be discussed here, this one is the biggest SIM. A big percentage of the cellular phone units available use the mini SIM. In the guide above, you can see that iPhone 3GS uses it. Since it is the biggest SIM, it will not fit in all the other devices listed on top.

    Micro SIM -- The micro SIM card was introduced when there was a need for smaller SIM cards to maximize space
    .
    The terminals of the micro SIM card and the mini SIM card are just the same; only the terminal plastic bed has been reduced. From the three SIM cards that will be discussed here, this one is the middle size. Using the right adapter, you can move a micro SIM card to a phone supporting a mini SIM, but not to a nano SIM phone.

  3. 3
    Nano SIM -- The nano SIM was conceived when the need for much smaller SIM cards were realized
    .
    Since the micro SIM's small size is still not small enough, the nano SIM's plastic bed has been totally removed, leaving the SIM terminal at a bare minimum, and at the same time making the SIM card smaller. Since only the unused plastic bed has been completely removed, and the SIM terminal has remained untouched, using the right adapters will allow one to use a nano SIM card in phones that require a mini SIM or micro SIM.
