   The SIM cover is on the front of the firewall. Unfasten the single screw to remove the cover.

2. With the chamfered corner (sloping edge) of the SIM facing towards the slot, gently push the SIM into the SIM 1 or SIM 2 slot until the SIM clicks into position.
   The SIM may get damaged if you attempt to insert it into the slot by the wrong end.

   SIM 1 is the primary SIM slot by default. If you intend to use only one SIM, it is recommended to use SIM 1 as the primary slot. If you want to use SIM 2 as the primary slot, you must manually configure SIM 2 as the primary SIM slot using the Web Interface.

   To eject the SIM from the device, gently push the SIM inward using a finger tip. Release the finger tip and pull out the SIM.
