我以前从未在 Linux 中使用过移动宽带，所以我不确定我要去哪里。
首先一些信息：
该 SIM 卡适用于我的 Android 手机中的数据。

有时我会看到这个弹出窗口：
如果我填写 PIN 码，它就会消失。当我暂停和恢复笔记本电脑时，我需要解锁 Gnome 密钥库。
演出节目nm-connection-editor：
然而，Gnome3 网络菜单没有显示它，即使我通过以下方式创建了它：
单击“连接”不会执行任何操作。
我怎样才能建立这个连接？
更新了还是没解决
运行后：
sudo systemctl enable ModemManager.service
sudo systemctl start ModemManager.service (typed PIN in popup after this)
sudo systemctl status -l ModemManager.service

答案1
显然它只是在 下被禁用gnome-control-center power。
切换此开关使我能够connect按 Gnome3 或
sudo nmcli con up <connection name>
一些用户界面反馈会很有帮助。
