Without more details on how the connection has been made through
qmicli and how the netdevice has been configured it is hard to tell.

I suggest directly using ModemManager so that everything is setup
properly, but if you still want to go with qmicli you can compare the
steps you are doing to the ones listed at
http://paldan.altervista.org/linux-qmap-qmi_wwan-multiple-pdn-setup/
that should be working fine.

Daniele
