How can we possibly enable GPS if there's no working SIM?

1. Download the corresponding QCOM: Obtain the necessary QCOM software for your 4G LTE USB Dongle by clicking QCOM_V1.6 & AT Commands. Ensure that the software is compatible with your specific dongle model.
2. Connect the 4G LTE USB Dongle to your PC: Insert the USB Dongle into your computer and install any required drivers or software that may be included with the device.
3. Access the QCOM software: Open the QCOM software on your computer, which should provide you with a user interface to manage the functionality of the dongle.
4. Send AT commands: Within the QCOM software, navigate to the command interface or terminal and send AT commands to control the functionality of the dongle. For GPS activation, the command "AT+QGPS" can be used. Sending this command will attempt to activate the GNSS (Global Navigation Satellite System) on the dongle. For more details about sending AT commands, please refer to Quick Start of LTE Dongle.
5. Verify GPS activation: Upon sending the "AT+QGPS" command, the response should indicate the status of the GNSS. If the response returns "1", it means that the GNSS functionality is enabled.
6. Consider GPS antenna placement: For optimal GPS reception, it is generally advisable to mount the GPS antenna outside the house or in a location with a clear line of sight to the sky. This will ensure better signal reception for accurate positioning.
