ZTE MF631

I have ZTE MF631.
PPP interface show that the device is detected, however even after inputting the correct apn and dial settings, it still can’t connect.
Does Mikrotik support this modem? If so, why is the logs showing “could not acquire serial port”?
Please help as we to confirm this immediately as we are nearing our deployment plan.

Thanks!
