我确实安装了 ubuntu，除了宽带连接之外，其他都不起作用。同样的 SIM 卡在 Windows 上可以使用。所以一般来说硬件和 SIM 不是问题所在。

如果我尝试启用，我会收到以下消息：

GD.Bus.Error.org.freedesktop.ModemManager1.Error.Core.WrongState：无法注册调制解调器：尚未启用

有人知道这里的问题是什么吗？

答案1

好的，问题在于没人说 fcc 锁。要使调制解调器运行，您必须执行以下操作：

sudo apt-get install libmbim-utils
sudo apt-get install libqmi-utils
sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
