I got my new iPhone X on launch day (November 3rd). Ever since then I haven't gotten voicemails or notifications for voicemails or anything. People tell me they left me a voicemail but I don't see it and I have no notification or evidence of it. It's super important that I'm able to get voicemails but ever since I activated my new phone I haven't been able to. Any idea how to fix this?
