I'm using Modem Manager on Ubuntu 18.04 LTS. Pay attention to modem 0:

SIM | dbus path: /org/freedesktop/ModemManager1/SIM/0
The SIM 0 operator is TIM:
root@flexiwan-vbox:~# mmcli --sim=0

| operator id: 22201
| operator name: I TIM
, and the relative apn are:
ibox.tim.it
wap.tim.it
I unlocked the sim, enabled the modem. But when I try to connect:
root@flexiwan-vbox:~# mmcli -m 0 --simple-connect="apn=ibox.tim.it,ip-type=ipv4v6"
error: couldn't connect the modem: 'Timeout was reached'
Why is this happening? It is like I can't reach the apn. The same happens also for wap.tim.it. How can I do? I've two modems, and I've done the same procedure for the other modem that has a Vodafone SIM. Everything works for it.
