Two Voicemail Notifications for Each Message

I get 2 notifications as well, but i know exactly why. It's because i have regular voicemail, and i have visual voicemail. Do you all have visual voicemail as well? If so that's the reason why your getting 2 notifications. If so just disable notifications for visual voicemail, and that should solve your problem. If that isn't the case then i have no idea what could be causing that to happen other than the duel Sims you were speaking about. Either way good luck with your problem, and i hope it gets taken care of very soon. 🤞
