NetworkManager not asking for SIM pin after multiple reboots
Summary
When the SIM pin is enabled and the device is rebooted, the device will ask for the SIM pin for the first time. However, starting from the second reboot, the device no longer asks for the SIM pin and Mobile Broadband connects automatically.
Version affected
nmcli tool, version 1.36.6
Steps to reproduce
[Test Steps]
- enable SIM pin
- restart PC
- unlock SIM pin
- connect to cellular
- do steps 2-4 again
Actual result
From the second reboot, the device no longer asks for SIM pin, and I am able to connect to Mobile Broadband manually.
Expected result
The device should prompt for the SIM pin on every reboot.
Relevant logs
Based on logs and some searches, it seems like NetworkManager saves and uses the network profile in order to perform automatic unlocks for the sim pin. May I ask if this is an expected behavior? it seems strange that SIM pin is only requested on the first reboot and not on the succeeding ones.
