LTE usb device modem without internal web server for the connection?

Hello.

I need to buy several LTE usb keys to use in a bonding system connection manager for live events.

For this purpose I need to buy lte key without embed webserver that provide the classic web page where the user use to connect to the service....

Fundamentally.. a normal clean LTE usb modem that linux don't see an ethernet adapter..

Any advice? Thank you.
