iphone voicemail notification not showing
When I first got my iPhone 6, I got the red dot on the phone app icon whenever I had a voicemail message. But about 2 months ago, this stopped working, and since then, I have only been able to determine whether I have voicemail by calling the voicemail number, which is VERY inconvenient. Since I have get 200MB/month of data (grandfathered plan), I do not normally have cellular data turned on; I mostly just have WiFi turned on unless I need the cellular data, so I do not rely on visual voicemail. This worked for me for many years with my iPhone 4 and worked on the iPhone 6 until about 2 months ago.
I have contacted AT&T both over the phone and in person in the store, and they have tried resetting my voicemail account and resetting all network settings on my phone, but the problem still exists. Does anyone have any idea on how to fix this? Thanks!
