EG25没有分配到IP

使用mmcli -m 0 --simple-connect=“apn=cmnet” 状态如下：

使用ip addr show wwan0 发现没有分配到IP，请问应该如何操作？
wwan0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN group default qlen 1000
link/none

mmcli -b 0 看看能不能看到ip地址。
如果看到了ip 地址
直接ifconfig wwan0 XX:XX:XX:XX

感谢回复，已按建议操作连上了Internet。但ip显示在 Bearer 1中，并非 Bearer 0，请问是什么原因？

mmcli -b 0 显示如下：

General | path: /org/freedesktop/ModemManager1/Bearer/0
| type: default-attach

Status | connected: yes
| suspended: no
| multiplexed: no
| ip timeout: 20

而mmcli -b 1可以看到ip：

General | path: /org/freedesktop/ModemManager1/Bearer/1
| type: default

| suspended: no

这是对象。默认应该还是对应模块的第一路。
关于这个对象为啥是0或者是1，没有研究过。
