Estoy usando un adaptador de red WWAN (Fibocom L850GL) que admite tarjetas SIM.
Mi sistema operativo es Debian 10 y hasta ahora necesito reiniciar mi computadora para poder usarlo.
Esto es lo que sucede:
sudo service ModemManager status
● ModemManager.service - Modem Manager

Lo he intentado sudo service ModemManager restart pero eso no ayuda:

¿Cómo puedo cambiar la tarjeta SIM dentro del adaptador WWAN sin reiniciar Linux?
