Re: How to enable AT commands of Foxconn T99W175 5G WWAN


1. Boot ubuntu from USB device
- I used Ubuntu 22 LTS, generated by Rufus app.
- You have to temporarily disable Lenovo secure boot.

2. Send AT command using ModemManager
AT^CUSTOMER=4
-> this command changes modem model type to DW5930e (probably DELL modem?) and it automatically opens COM port ...
