No notifications of new voicemails on iPhone despite being able to play them
Recently upgraded from iphone 5s to iphone 8 and also changed providers, had 5s call forwarded to new iphone 8 for a month to be certain i would be satisfied with coverage ect. Everything wad 100%, voicemail worked fine. After cancelling old service provider my voicemail stopped showing notifications but were accessable, just didn’t know i had any. After hours of tech support and reading different forums I decided to backup my old phone to my computer and restore to new phone. Now everything is working fine.
Hope it helps someone.
