Does Flint AX1800 support WAN from 4G USB?

I’m using 4G to connect Internet via 4G USB. Can I also connect USB to Flint AX1800 and the router use 4G as the main WAN for Wifi? Is it stable? I’m still waiting for the next AX router from GL.inet that support 4G/5G from the direct sim card…

technically all of the recent gl inet products supports 4g internet via usb tethering or modem mode, i tested it in two different models and more basic than ax 1800, the mango router and sf1200 with no issues, i have the ax 1800 as my main router and works very well, take into account when you are using 4g connections you must adjust the ttl value in order to share your internet but can be adjusted easy in the firewall of luci
