Good to know, but does not affect me in Europe. Thanks

select your provider in network setting, instead of automatic

It would be easier if could automatically prefer the SIM provider, and one switched roaming on and off. That is what some people expect.

Also, what you suggest does not allow roaming data but not voice.

? settings; system; mobile network;select network automatically?
I guess not only data

from user guide:
The remaining settings allow you to choose your 2G/3G preferences, and let you pick a mobile network manually if you want to.

Yes, I can pick a network manually if I want no roaming, but how would you configure it to roam only data?

Is it possible to do that on others OS? Just don't open the phone app =)

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:

http://www.geckobeach.com/cellular/secrets/gsmcodes.php

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.

This is supposed to be user friendly?

My mum has my jolla phone so I can't check... is there no 'barring' menu in the phone? I know there is one that sorts out diverts to voicemail etc - usually the roaming bars would be in that part.

I knew nothing about barring, and I've had cellphones for 20 years. I was just expecting to disable roaming.

pulsar ( 2014-11-28 00:31:07 +0200 )edit

I don't want to bar. I want people to be able to call be and if a tower captures me, just drop it. Also barring does solve that if you start a call, it might roam in the middle.

Note that we are now talking about a use case where you care about continuing to use data, but not about dropping calls. You may have a data roaming package, but not a voice roaming package.

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.
