### 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.
