如何在不重新啟動 Linux 的情況下更換 WWAN 轉接器中的 SIM 卡?

如何在不重新啟動 Linux 的情況下更換 WWAN 轉接器中的 SIM 卡?

我使用的是支援SIM卡的WWAN網路適配器(Fibocom L850GL)。

我的作業系統是 Debian 10,到目前為止我需要重新啟動電腦才能使用它。

這是發生的事情:

sudo service ModemManager status
● ModemManager.service - Modem Manager
   Loaded: loaded (/lib/systemd/system/ModemManager.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2019-12-12 21:28:52 CET; 25min ago

           ├─ 911 /usr/sbin/ModemManager --filter-policy=strict
           └─1186 /usr/lib/libmbim/mbim-proxy

我已經嘗試過,sudo service ModemManager restart 但這沒有幫助:

   Loaded: loaded (/lib/systemd/system/ModemManager.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2019-12-12 21:55:07 CET; 39s ago
