Voicemails delayed on iPhone

Apple has absolutely, literally, positively, nothing to do with the delivery of voicemail or its notifications. It is absolutely, 100% a carrier provided feature.

Yes, carriers blame Apple and Apple blames carriers from time to time, but in this situation, Apple has every right to blame the carrier, because isn't a carrier, they don't deliver voicemail or notifications of voicemail.

Anything is possible, but the assertion the phone might be delaying the notification is highly unlikely. HIGHLY UNLIKELY. The most likely culprit for this user is the use of a MVNO carrier, who gets their service from a prime carrier. There are just too many hands in the chain of delivering voicemail messages going the lesser expensive route of using a MVNO.

I've had friends go the MVNO route to save money, only to have loads of issues, like delayed voicemail messages. There's an old saying........"you get what you pay for."

I am on Verizon not a MVNO. So unfortunately that is not the reason. This issue has been reported on every major carrier in the US.

With all the millions of people who have cell phones, I'd be surprised if it wasn't reported on every carrier. Unfortunately, that doesn't tell us anything. Delayed notifications can be caused by many different things. It's like saying, "I have a fever." That doesn't tell you much about what is making me feel ill.

With Apple and Verizon not working together what our options?

What sometimes works with misbehaving carrier features is to have the carrier remove the feature from the account, let the account refresh in the switch (takes about a minute) and then add the feature back. In the case of Voicemail, it might be more than one feature: voicemail and voicemail notification. Depending on the carrier, there may be a third feature, visual voicemail. And no, it doesn't always work.

I don't know if this is helpful, but I have noticed that sometimes no voicemail appears until I open the Phone app. Then the Phone app icon gets a (1) on it and the voicemail appears. It's not always the case, sometimes the voicemail will show up on its own and notify me a few hours (or a day) after the message was left. It appears that the Phone app is doing something to "notice" that there is voicemail when I open it.

There can be lots of reasons.

I don't see VM notifications for a lot of people until the end of the day as I have a work Focus that does not permit my neighbor to interrupt me with a request to buy him more birdseed.

I have AT&T and my voicemail messages are never delayed. I'm on iPhone 15 Pro Max and now the latest iOS 17.1. If it's a bug in iOS, it's a very selective bug, which doesn't effect me or our other iPhone 15 Pro, also on iOS 15, or anyone in my office with iOS 15 on any number of models of iPhone.

You need to contact AT&T as this is not an iOS bug.

I’ve been having the same issue on T-Mobile for a few years now. I 100% know I have some voicemails that will show up in a few days. It is incredibly annoying. I’m also struggling to believe that it is the carrier since in this thread I saw issues (at least) with Verizon and AT&T as well as my carrier.

It’s happening to me. I have AT&T. I’m on an IPhone 13 Pro Max. Version 17.0.3

It may be happening when voicemail messages are coming in when I’m on airplane mode. Messages are showing up several days late.

I should add, it’s not just that the notifications didn’t appear. I never got the voicemail message. Not until days later. I called AT&T and they said they fixed it, but we shall see if they really did, or just said they did.

I was having this problem and commented a week or so about it. I knew I had some voicemails in the system even though it wasn’t showing in my phone app. I dialed my phone number from my iPhone, put in my code, listened to the 26 voicemails that I had and ever since, my voicemails have been showing up on time.

Yes, I have a business and my clients messages are delay hours to days. However, Verizon gas lights me and blames it on my phone (iPhone 14 pro) which I keep on all software updates. I’ve probably lost new business too. ITS NOT THE PHONE!
