I have a constant notification for a voicemail that I can’t clear unless I call the dumb voicemail number for t mobile and do a bunch of annoying stuff to listen to it then delete it when I don’t ever wanna use that because I have visual voicemail instead that works way better. I can’t turn off phone notifications so it won’t go away permanently. I don’t want to have to call a voicemail number each time this happens I just want my primary and only voicemail to be visual voicemail. Tried googling stuff but couldn’t find help because it just says turn notifications off for phone app but it won’t let me and I’m not even sure I’d even want to do that.
