过去几天我一直在尝试在我的新 ubuntu 盒子上设置 GSM 连接。但是，我似乎无法让网络管理器正确管理它。盒子是compulab fitlet2，手机卡是simcom 7100A。

但我收到这个错误
$ nmcli con up vzw
Error: Connection activation failed: No suitable device found for this connection.
我也无法告诉 nmcli 设置设备
$ nmcli device connect cdc-wdm1

任何帮助将不胜感激。谢谢
答案1
从“Status | lock: 'sim-pin2'”行看来，该卡在开始连接之前需要 PIN。
我遇到了类似的问题，但来自 mmcli -m 0 的消息是“sim丢失” - 它很好地解释了我与“设备不可用”的所有问题。 SIM 卡已就位，但接触失败......
