"No voice-capable modem available" after unlocking the SIM

What problem did you encounter

It seems that Calls is not aware when my sim card is unlocked. Before unlocking it I cannot place a call and see "No voice-capable modem available". After unlocking my SIM, I keep getting the same message. Then if I fully kill calls and reopen it, it is then letting me place a call.

What is the actual behaviour?

I cannot place a call. I get "No voice-capable modem available" message.

What is the expected behaviour?

I should be able to place a call once my SIM card is unlocked

How to reproduce

  1. Reboot the devkit
  2. Go to the setting and unlock the SIM card
  3. Open Calls and go to the dialler panel
  4. A message "No voice-capable modem available" is visible instead of the "call" button.

Workaround :

  1. Open a terminal
  2. Enter "killall calls; killall calls; killall calls; killall calls" and validate
  3. Open Calls and go to the dialler panel
  4. It is now possible to place a call
