The SIM card reader for 3 V and 1.8 V SIM cards is located on the front panel of the router.

Before handling of the SIM card turn off the router and disconnect it from power supply.
Press the small yellow button to eject the reader holder. Insert the SIM card into the reader
holder and slide it in the reader (see figure below).
