Missed call notifications when not available

I have found that it was possible to use the number 12337 but does not work anymore as described here:

Any solutions how to fix the missed calls notifications?

Hi @Natasja ,

Do you think the problem is the Phone App? I think the problem is somewhere else. When the phone is switched off I still do not get sms notifications that somebody called me. I would like to have such notifications as in the image 

Hi @Natasja . Just to follow up on the issue. Yesterday I called customer service and they told me that I have to go to KPN shop as they can only do it in shop as it is configuration of the phone. Today I spent 1 hour in KPN shop in Rokin Amsterdam. Very helpful staff but could not help. It seems that the problem is with calls forwarding but neither in shop not can could change it. We compared configuration of calls forwarding on a other Galaxy S10 and the calls are forwarded to strange number +31653(your number) but on my phone everything is disabled. We checked also voicemail settings but they are correct (we tried activation and deactivation of voicemail plus messages). To cut the story short nothing worked and we were unable to set call forwarding as this option is disabled in KPN system but also manual on my phone is not working. I hope that technical service will find the root cause. Below scree of call forwarding (as I said before, manual changing does not work as you get error see also below)

Dear @Natasja , unfortunately your colleagues at KPN shop could not solve it even with help from customer service which was assisting them for almost 1 hour. 

I did try other phone but it did not help. My wife who has also S10 also has the same problem. Lady at KPN shop had S10 also and for her it was working (as I wrote above for her call diversion settings were active while for me and my wife are not active and cannot be changed). I think we ruled out the phone issue and I think it is from your side.

About phone reset- do you mean phone app and removing cache and all data from this app? I did it three times already. If you mean something else the please explain what I need to do. Thank you

Hi @Natasja. I finally figured out the answer for my question (at least in my case).

And the answer is: It is not possible to have only notifications on and voicemail off. To get notifications you need to still have voicemail enabled. 

In my case I disabled the voicemail by sending sms UIT to 1233  and this also switches off both the voicemail and missed calls notifications. The missed calls notifications are part of voicemail so you cannot have only notifications without voicemail. Blocking leaving voice messages does not help as people are still forwarded to voicemail (in other words people calling you will pay for the call which is not the case when you do not have voicemail). I am an expat so a lot of people call me from abroad and activated voicemail cause extra costs for my friends. I think current configuration of missed calls notifications and voicemail could be improved. I know that in other networks both services can operate independently and this is what I would like KPN to change.

To summarize: again I am very disapointed as it took me multiple calls to customer service, contact from your technical department two visits to KPN shops and trying to find the answer on the forum to understand the problem and finally I figured it out myself by testing different settings. I just want to add that every time I contacted KPN about this problem I got different answer. And Technical Department tried to convince me that they did not do anything to settings and miraculously notifications started to work. This was final clue that helped me. It seems that they reset/enabled voicemail for me although technical department was saying they did not do anything apart from sending me sms that I need to configure my voicemail. I do not expect all people to know but at least technical department should know what to do.  Thank you for help and could you forward my suggestion of separating voicemail from missed calls notifications?

P.S. Another thing I noticed. In principle, first configuration of voicemail has to be done in The Netherlands but it can perfectly be done via KPN voicemail app. This is something I do not understand- why calling from your own number in roaming you cannot set up voicemail but KPN voicemail allows it. This should be consistent. I understand that calling from abroad and from different answer you are not able to set up voicemail for your number but from you number it should be allowed.

Dear @Natasja . Thank you very much for help. Please let me know if you receive any reply from the tech department. Maybe there is a way to enable notifications in a different way? The way it is set up now is strange for me and I hope it can be changed in the future.

Dear @Natasja. Thank you for reply. Maybe something for the future to consider- I had Tmobile and Vodafone before KPN and none of them required voicemail for missed notifications to work (in other words I had voicemail off and notifications were working). I also have Polish simcard in my Galaxy S10 and notifications work perfectly without diversions to voicemail. For all networks I mentioned missed calls notifications are working independently from voicemail.  In this way you avoid people from abroad being charged when you are not available.
