I've been having this same issue for weeks. Resetting network settings does nothing. Sounds like just throwing things up against the wall hoping something will work. Problem seems to be on your end, not our end.
I’ve also been having this problem for weeks.
Pretty lame answer of turn your WiFi off! Really turn WiFi off and use cellular data all the time instead so you can charge us for going over? Um, No!
We can relate to your need to receive your voicemail messages in a timely fashion. When this happens are you connected to a WiFi network? Because voicemail is a cellular feature, your cellular network and data must be connected. What happens when you turn WiFi off, and have someone leave you a voice message?
This is happening to me, too. I missed a call from my work offering overtime pay, which I could have really used. I have an iPhone 7+. I have tried all of the suggestions in this thread. This happens when I’m on WiFi or LTE. I have no problem
with any other phone functions.
Thank you for the information provided so far. We want to look further into what is going on with voicemail service. Do any other devices in the area have the same issues? Can we have your ZIP Code to look over the area? Is it happening only at your home location? We see a lot of troubleshooting has been attempted; has the device been factory reset? If this is done, please try your service before restoring your device to ensure it is tested as if it was new. Let us know if anything changes.
I have been having the exact same issues over the last 1-2 months on my iPhone X. I have missed some important voice messages due to this. They seem to come in batches to my phone. I've been on and off Wifi, so I don't think this is the issue. Today I got one voice message right away when I was on wifi and at the same time got a voice message from 1 week ago. Since I do get away from my house and drive to work every day, I am on the cellular network at least twice a day for 30 minutes at a time during my commute. With a lot of us having this issue including one of my coworkers who is also on Verizon, I do not think this is an issue of Wifi. There must be a network issue with Verizon that is causing this.
I am having this issue, too! I just had 6 messages come thru some of them from March 11 thru today. They come in batches. Last time it was 7 messages at once, some of them were 3 weeks old.
