very delayed voicemail notifications

I’ve been having the same problem for the past month or so. (Sprint). I think I may have figured it out, at least for now. Make sure to delete old voicemails, and if you have done that, scroll down and click on deleted voicemails and clear all. I had hundreds of voicemails sitting in the deleted file. As soon as I cleared them, new voicemails from days ago popped up. Hope this helps

You must have cellular data turned on to receive visual voicemail. If it is and you still aren’t getting it you need to contact your carrier, as they manage voicemail.

Do you have Cellular Data enabled? It is required for Voicemail notifications.

You need to work with AT&T tech support. Everything involving voicemail is under the control of the carrier. Assuming, of course, that you leave cellular data on all the time.

I have never had a delayed voicemail notifications in the almost 14 years I have owned iPhones. I don’t know if this has been pointed out to you before, but you must have cellular data turned on all the time to receive voicemail alerts and updates.

I saw a post where someone deleted most of their old voicemails and it helped them get voicemails more quickly. I tried the same thing and it seems like it helped. Too bad Apple and AT&T can’t figure out how to fix this.

And do you have cellular data turned on?

So far so good after deleting my old voicemails. FYI, it’s not just AT&T. I’m with Rogers in Canada. So I believe this is a broader Apple issue.

I delete my messages, and also go to delete and press “clear.” Don’t know if you’re doing that as well. I have seen an improvement and getting my voicemails when I do this.

The carriers are aware and have not been able to solve this serious, longstanding (years) issue. Multiple failures of full troubleshooting. It is apparently a joint iPhone/carrier issue needing collaboration.

My wife’s iPhone 12 Pro Max also has this same issue since upgrading from an iPhone 7 in Nov. I also upgraded from android to just the iPhone12 at the same time and dont seem to have the issue. Along with missing Visual VM (hitting *86 they are waiting at Verizon VM system) she is also at times not getting the inbound call and does not get any indication of a missed call.

We keep applying the latest iOS hoping the fix the issue. Verizon also sent us a single booster to install in the house because we only had 2 bars but problem seemed like it was fixed but still continues. I have about 4 technical support tickets opened with 3 of those escalated to higher level of support. Next I am going to push to see about getting a replacement phone.

My wife and I both have the iPhone 12. I have this problem but she doesn’t. Both have cellular data on but she has cellular data roaming ON. I just turned mine on so I’ll see if the problem gets resolved and let everyone know.

This is a major (carrier) problem! It is years long and AT&T has not addressed it. I don’t think they can figure it out. I’m trying to learn if it’s as bad with Verizon. It’s unacceptable.

My cellular data is on and I never turn it off, like most of us. Still, I am getting voicemails days later and it picks and chooses with which voicemails it wants to do this with. I am on Verizon, it is so frustrating.

This has been a problem for a while
