Debian Jessieでモバイルブロードバンドのトラブルシューティングを行うにはどうすればよいですか？
Linuxでモバイルブロードバンドを使ったことがないので、どこに行くのかわかりません。
最初のいくつかの情報：
SIMは、私のAndroid電話のデータに対して機能します。

時々私はこのポップアップを見ます：
PINを入力すると、消えます。ラップトップを一時停止して再開するときは、Gnomeキーストアのロックを解除する必要があります。
nm-connection-editorショー： 
ただし、これを使用して作成したにもかかわらず、Gnome3ネットワークメニューには表示されません。
「接続」をクリックしても何も起こりません。
どうすればこれを接続できますか？
更新しましたが、まだ解決していません
実行後：
Sudo systemctl enable ModemManager.service
Sudo systemctl start ModemManager.service (typed PIN in popup after this)
Sudo systemctl status -l ModemManager.service

どうやらそれはgnome-control-center powerの下で単に無効にされました。
このスイッチを切り替えると、Gnome3またはでconnectを押すことができました。
Sudo nmcli con up <connection name>
少しのUIフィードバックが役に立ちました。
