従来の3Gモデム（Telit HE910）に問題があります。接続は Netplan と ModemManager を介して確立されます。 Ubuntuはモデムが正しく認識された状態で起動し、SIMカードも問題なく認識されます。奇妙に接続されたようですが、モデムがすぐに切断されますね。デバッグモードでModemManagerを起動しましたが、実際の問題がどこにあるかを理解するのに十分なモデムに慣れていません。

これは驚くべきことではありません！
あなたのモバイルネットワーク事業者に見えるVodafone Italia Omnitel（あなたのAPNがiliadによって制御されているように見えますが、これは一種のローミング契約ですか？）は2021年に3Gネットワークを終了しました。したがって、接続を確立できません。
したがって、モデムを2G（または2.5〜2.75G、つまりGPRSまたはEDGE）サービスに使用し続け、システムにそのサービスを許可するように指示し、それを許可する購読をしない限り、これは電子廃棄物です。
