To follow up on this, I used a Huawei E397 to bring up dual-stack IPV4V6 context successfully with ModemManager and NetworkManager. First, make sure the APN you're using is known-good (otherwise you'll get CallFailed errors) and that the profile in the modem that matches the APN is a V4V6 context. If it's not, for now you can set that context via AT commands by: AT+CGDCONT? AT+CGDCONT=<profile number>,"<apn>","IPV4V6" and the modem should update. Then you can connect with either mmcli or NetworkManager. If you get the bearer's IP details it'll look like this: Bearer '/org/freedesktop/ModemManager1/Bearer/5' ------------------------- Status | connected: 'yes' | suspended: 'no' | interface: 'wwp0s20u1i3' | IP timeout: '20' ------------------------- Properties | apn: '<a href="http://epc.tmobile.com" rel="noreferrer" target="_blank">epc.tmobile.com</a>' | roaming: 'allowed' | IP type: 'ipv4v6' | user: 'none' | password: 'none' | number: '*99#' | Rm protocol: 'unknown' ------------------------- IPv4 configuration | method: 'dhcp' | address: '<a href="tel:30.178.21.152" value="+13017821152">30.178.21.152</a>' | prefix: '30' | gateway: '<a href="tel:30.178.21.153" value="+13017821153">30.178.21.153</a>' | DNS: '10.177.0.34', '10.165.228.68' | MTU: '1500' ------------------------- IPv6 configuration | method: 'dhcp' | address: '2607:fb90:1900:c650:f87f:85a7:cacb:ee86' | prefix: '64' | gateway: '2607:fb90:1900:c650:6018:a203:242d:42fd' | DNS: 'fd00:976a::9' | MTU: '1500' You can either use something like NetworkManager to do the IP configuration, or do it yourself. "DHCP" here really just means "automatic", which for IPv4 would be DHCP and for IPv6 means SLAAC + DHCP (if the modem requests you to run DHCP via the "O" or "M" flags in the RA).
