Quectel RM551E-GL

Yep registered, even though Quectel Navigator itself shows as unregistered, must be depending on creg response too. It should now actually work in any mode when using correct settings. Since it works with rndis, apn must already be correctly set, but let's confirm with
Code:
AT+CGDCONT?

I use the quectel ec25e. When it switches to Jio4g, even creg might show registered, which is a quectel quirk. Anyway, that is not material to our issue.
Is it already in mbim mode? If not put into that mode and restart
Code:
AT+QCFG="usbnet",2
AT+CFUN=1,1
Some important things to note with this
1) Make sure you've installed the mbim driver from page you linked 12.81 MB file on MEGA
2) In network connections, make sure the quectel connection is using the mobile broadband interface driver and not ecm, ndis or some other quectel driver. If not, change it manually by configuring the adapter and updating driver manually to the mobile broadband one.
If after all this, it's not done, we may have to manually start the connection. Provide responses for
Code:
AT+CGACT?
AT+CGPADDR
