network.loopback.proto='static'
network.loopback.ipaddr='127.0.0.1'
network.loopback.netmask='255.0.0.0'

network.lan.netmask='255.255.255.0'
network.lan.ip6assign='60'
network.lan_dev=device
network.lan_dev.name='eth0.1'
network.lan_dev.macaddr='40:d6:3c:1f:4f:a1'
network.wan=interface

and this is my uqmi curent setting :

# uqmi -d /dev/cdc-wdm0 --get-current-setting
{
        "pdp-type": "ipv4-or-ipv6",
        "ip-family": "ipv4",

        "ipv4": {
                "ip": "10.2.162.185",
                "dns1": "10.255.255.254",
                "dns2": "8.8.8.8",
                "gateway": "10.2.162.186",
                "subnet": "255.255.255.252"

Yes i have ipv6 even in this openwrt version with 3g / UMTS protocol
Only on qmi protocol there is a problem

'3g / UMTS protocol' means PPP ?
What is your modem, BTW ?

ok . i want ipv6 in qmi proto in my router

i test this protocol in unielec u7628 device and i have same problem

What is the modem? You mentioned the router where the modem is built in, but never the modem itself.

lsusb, usb-devices

or similar would help.
Some (old) modems don't support ipv6.
