Cant delete voicemails ios 26.3

[maerz001]

Hi. As title says i cant delete voicemails on ios26.3

I got a sim card while on holiday in costa rica with kölbi.
Soon after i got 3 voicemail spams as the number was not shared to anyone.

I cant delete them as the button is greyed out. When i call the voicemail i get some spanish which i dont understand.
since a weeks the notification pops up every day about them which is annoying.

Any idea?

Sounds like your carrier made their own VMs un-deletable.

Well but i even can’t mark them as read. So i have for 10days now the red dot on the phone app and multiple infos coming from notification center about the voicemails daily
