select your provider in network setting, instead of automatic

You can bar incoming and outgoing voice calls at a network level using standard GSM codes. Most phones implement menu options for doing this and hence dialling the codes automatically. I haven't got the jolla phone to hand to see if these menus exist but have a look at:

as you can dial the numbers on the keypad yourself. The call barring PIN is different from the SIM pin. Try the obvious 0000 or 1234 etc if you don't know what it is.

Ok, so @pulsar I got some information from a friend working in a MVNO company.

If your phone is off, your Operator knows that you are not connected (because your SIM can not send its ID for network authentication), your Operator will not make the call and just send it to the Voicemail. So you will not be charged except mistakes from them that you could claim.

If your phone is on, you could get a bill for an unanswered call that would land in your Voicemail:

• This is forbidden in Europe!
• In the rest of the world, it depends on the Operator's technology. It is called ORLCF (Optimal Routing for Late Call Forwarding). If your Operator does not have this function, either he will charge you, or he will take the charges himself (this options, due to claims, is nowadays more likely but not 100% sure)

So the best answer for you is to check with your Operator if he uses ORLCF. And if not, if he actually does charges you for unanswered calls.
