Automatic call disconnection after 15 minutes

Hi @Adityaa . Welcome to the forum.

No, this is not normal. Are you talking about mobile phone or a landline?

Hi Erwin, Thanks for responding. 

I am talking about my mobile phone xxxxxxxxxxx

Do you have a physical SIM card? Or an E-SIM? 

If you have a Physical  SIM, can you try to use it in a different phone?

I am having Esim

What kind of phone do you have?  And did this issue suddenly appear? Or was it always this way?

I am using iPhone 12, and I checked for the phone setting. There is nothing in the phone. I usually don't make direct calls so didn't realize so far. 

This is happening when I make a outgoing (direct) call to international numbers.

And is this only to international numbers? Or also local numbers?  And does it make a difference if you call a mobile number of a landline? 

(dit you try resetting the iphone too?)

Hi Erwin,
I did reset my iphone too. But still the issue is same. This is happening only to International calls to mobile number, I didnt try to landline. Just yesterday I called to International mobile and as usually it got disconnected automatically at 15 mins

Most likely this has something to do with your iPhone.  Maybe visit a KPN shop in your neigbourhood and have it checked out?

@Adityaa do you make an direct call or do you use an carrier pre-select for this call? If you make an call by using an carrier pre-select it’s possible that they use these settings.

carrier pre-select operators let you make international calls for an lower price rate then KPN

@Speedmaster KPN sim I am using is from my company. Is that what you mean by pre-select? When I called to KPN customer care they even said they cannot locate my sim details on my name.

Thanks @Speedmaster for understanding the issue and for your time
