The device is compatible with mini-SIM (2FF) size cards. But since different types of SIM cards have the same contact arrangement, smaller SIM cards can also be used with the router, provided they are inserted into a 2FF SIM card adapter. A size perspective of the most popular SIM card types can be seen in the figure below:
