The QMI interface is displaying "network device is not present". It goes off automatically after reboot since I switch it ON manually.

You should not reboot.
Delete wan1 (DHCP). Run logread -f
Open another console connection and switch the USB configuration as shown above, then configure QMI interface.
Show the log data collected.

All looks good, hovewer:

Check if SIM is properly inserted, restart the interface and see if there is any change. You may need to add an extra delay to QMI interface [in /etc/config/network] with option delay '10'

Alternatively, check from a terminal:
picocom /dev/ttyUSB2
then send AT+CPIN? and AT+CIMI
For the 2nd command there is no need to share the complete response, we're only interested in the possible error.

Please how will I do this?
The picocom didn't work.(not found)

With any editor, like vi or nano.

It should be installed if you followed the instructions.

Yes, I need to install picocom again, it was installed and later i removed it.
With the editor, vi or nano, I need to learn more about them in order to use.

There could be a problem with the SIM slot, the SIM works in a different router.

You need to fix this before proceeding with the configuration.
Make sure the SIM is plugged in correctly. As I remember (not 100% sure) it needs to be positioned with the contacts up and a cut away from you.

I will do as you have said and give feedback.
Thanks!

Make sure the APN name is correct and change pdptype to ip
If you think a delay is needed you can add it in the configuration file manually.

Not the latest, but...

Are you confident that internet is the right APN for your carrier?

0,1 means "Registered, home network"

All looks good, so let's add to the QMI interface configuration
option 'timeout' 30
then restart the interface and re-check the system log.

I can not find this in the QMI interface. For the APN , "internet" is correct.
