== Notes and version constraints ==
* The complete AT command set is in the SIM7600X Series AT Command Manual V3.00 – only selected commands are listed here.
* Firmware updates require administrator privileges and a high-quality USB cable; if they fail, reinstallation of the update tool may be needed.
* The 'chmod 777 sim7600_4G_hat_init' command assumes the file exists in the current path; otherwise the sample program must be downloaded, extracted, and copied to /home/pi/SIM7600X.
* In rainy weather, the time to first GNSS fix increases significantly.
* Network mode selection via AT+CNMP? is version-sensitive; exact values must be confirmed in the AT manual.
