To install the SIM card in the GeoSIG GXX-4GUE 4G Modem, please follow these steps:
1. Make sure the SIM card is not locked by a PIN code and that the modem is not powered.
2. Open the housing of the modem by pushing down the four screws on the corners of the housing using a screwdriver and turning the screws approximately 45° counterclockwise.
3. Use a pointed tool, such as a screwdriver, to press the small yellow button and open the SIM card slot. If needed, you can carefully remove the USB connector (green & green/white wires) and the antenna for better access to the SIM card slot.
4. Add, remove, or change the SIM card as needed and push the slot back into place.
5. If you removed the USB connector and antenna, reconnect them.
6. Close the housing of the modem.
7. Connect the cable to the SERIAL connector of the GMSplus, which functions as a USB port.
For visual reference, please refer to Figure 2 in the GeoSIG GXX-4GUE 4G Modem User Manual.
Note: It is important to ensure that the SIM card is compatible with the modem and that you have the necessary APN, login, and password provided by your mobile phone provider for proper configuration.
