The SIM card size that is supported on the Digi TransPort and Digi Connect WAN family of devices is called any of these names:
1) Mini SIM card
The Digi devices DO NOT take Micro or Nano type SIM cards. Adapters can be used to adapt Micro and Nano type cards to a Mini size, but these are not tested by Digi International, so results may vary if these are used in the devices.
