ModemManager auto connect HUAWEI ME909s 821ap V2 4G Module

I have HUAWEI ME909s 821ap V2 4G Module, connected via usb.
I have cellular configuration file with apn, number, etc. but autoconnect not working as my device goes offline.
With WiFi connection I checked from web-console and see modem in modemmanager list:
