Setup MC7455 connection to internet with modem manager

[Nassim Dahmani]

Yes the device is unmanaged I searched on internet how to set it managed by
NM but nothing helped me

nmcli dev show cdc-wdm1

GENERAL.DEVICE:                   cdc-wdm1
GENERAL.TYPE:                           gsm
GENERAL.ADR.-MAT.:                      (unknown)
GENERAL.MTU:                            0
GENERAL.STATE:                           10 (not managed)
GENERAL.CONNEXION:                      --
GENERAL.CON-PATH:                       --

I'll wait for a return of Thomas Haller thank you for your help
