MicroSIM cards slots

Fig. 4.6: MicroSIM cards slots

The M!DGE router is equipped with two MicroSIM (3FF) cards slots which are placed under a SIM card cover. Use PH0 screw driver for its opening. If using only one SIM card, use holder one.

The SIM card holder has a locking mechanism – for opening pull the front part of the holder down and then you can open it. After inserting of SIM card (cropped edge left, connectors down) see picture, close the holder and lock it.


Power off the rourter before inserting the SIM card.

4.2.5. Screw terminal

Screw terminal plug type Stelvio Kontek CPF5/15 or MRT3P/15V01 can be used.

Reset button

Fig. 4.8: Reset button

The Reset button is placed close to the USB connector. Use a blunt tool no more than 1 mm in diameter (e.g. a paper clip) to press the button.

The reset button has two functions:

  • Reboot the system

    • Press at least 3 seconds to release a system reboot.

    • The reboot is indicated with the red blinking STAT LED.

  • Factory reset

    • Press at least 10 seconds to release a factory reset.

    • The start of the factory reset is confirmed by all LEDs lighting up for a second.
