SIM Card Slots

Slots for two SIM cards are located on the right panel of the router under a metal cover. It is
necessary to insert an activated SIM card, to work properly. If the PIN is required for the SIM, enter it
in the router's web interface. The SIM cards may have different APNs (Access Point Names) adjusted.
The SIM card changing procedure is described below.
Type of SIM cards: micro-SIM (3FF) 15.0 × 12.0 × 0.76 mm.
NOTE
Inserting the SIM card:
Always disconnect the router from the power supply before handling the SIM card.
Unscrew two screws on the SIM card cover and remove the cover.
CAUTION
To remove an inserted SIM card, use the flat end of a spudger, or your fingernail, press the SIM
card slightly into its slot until you hear a click. After hearing this click, release the card, and it will
pop out of its slot.
To insert a SIM card, push card into the slot until it clicks into place.
Place back the cover and fix it by two screws.

Cellular Antennas

Main (ANT) and diversity (DIV) antennas can be connected to the router using the SMA connectors
located on the front panel.
Do not run the router without connected cellular antenna connected to the main antenna
connectors as the energy from the transmission is effectively reflected by the open end and can
damage the equipment.
CAUTION
NOTE
Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.
The diversity antenna improves the radio capability of the router at low signal strength.
