Different modes of EG25-G

I’m using EG25-G on Windows 10 and I wonder what’s the best USB mode to set?
I need it to be connected when I turn on the PC and keep a stable connection.
Got confused with all the option of MBIM, RNDIS etc.
Thank you!

To tell the truth, each network card mode is very stable. You can use that mode if you are more familiar with that protocol.
