もう一度Tools for the Fibocom L850-GL / Intel XMM7360 LTE modemのサイトを眺めていると”FCC Lock”の記述があります。
mmcliでモデムを確認すると、Statusでdisabledになっている部分があるのですが、こちらの影響でしょうか。
$ mmcli -m 0

もともと人柱覚悟で始めたことですのでFCC Lockのところに記述されているATコマンドを実行してみます。

Statusがenabledになりました！
ところがnm-connection-editorでMobile NetworkのAPN設定をおこなっても接続できません。。。そう簡単にはいかないものですね。
