Initial power up of Discovery 2G Plus RS232

How to insert Micro-SIM card

• Remove the cover: Gently push the top and bottom cases of the Discovery 2G apart with both hands to open the device.
• Insert Micro-SIM: Place the Micro-SIM card into the SIM holder, ensuring the cut-off corner faces away from the slot.
• Replace cover: Securely attach the device cover back into place.

• Your device is now ready for connection.

For optimal performance and to prevent damage, always ensure the device is fully powered off—with both external power and the internal battery disconnected—before inserting or removing the Micro-SIM card. Failure to do so could result in a damaged Micro-SIM card or the device failing to detect it.
