SIM Card Insertion

To insert the SIM card into a ReXgen Air device, open the SIM slot lid correctly and carefully.

Locate the SIM slot: Open the SIM cover and identify the SIM slot.

Check orientation: Hold the SIM card with gold contacts facing down and the cut corner aligned with the slot.

Insert only into the SIM slot: Slide the SIM card straight into the slot until it stops. Warning: Do not place the SIM anywhere else: it may fall inside the logger.

Close the cover: Once fully inserted, reattach the SIM cover.

Ensure the SIM is inserted, as shown, in the images above (chip facing down).

Mishandling the SIM slot lid may damage the device and the SIM card inside.
