Voicemails delayed on iPhone

I’ve tried all of the steps above and they didn’t work for me either. It’s definitively an iOS iPhone issue. I’ve had this issue for years. Toggled and played with settings and even upgraded my phone. This isn’t a carrier issue. This is an iOS issue for sure and I’m disappointed Apple has refused to address this or fix this for years.

This EXACT issue has been happening to me since I bought my iPhone 14. And I’m a TMobile user, so it’s certainly not a Verizon issue. I’ve never had hours of delay to receive a VM notification. And it’s not even a notification issue—- the actual VM never shows up until randomly hours or a day later. LOTS of missed messages and unnecessary Delays esp with business calls. This is a problem. YES- I have restarted my phone many times. YES- I’ve gone in to settings - phone - etc. YES- I have the latest iPhone updates. NO- this didn’t happen with my iPhone XS while still using same carrier TMobile. This isn’t a carrier issue.

I have an iphone 12 pro running ios 16 on AT&T and I’ve had this problem for years. I usually just have to restart my phone for them to pop up if I’m expecting a call back from someone, otherwise they always pop up hours or days later. It’s very annoying and as of the day of this post, even restarting my phone doesn’t work. I just had a missed call and saw an icon for a new vm and when I opened it the icon went away and there was no new message showing. Very frustrating since I use my phone for work.

I am also having the same exact issue. I’m using an iPhone 13 Pro Max with the current iOS 17.3. All other settings and updates are installed. I am running on AT&T. This started around iOS 17.2 for me. The call will come in and then a voicemail will show up randomly. It could show up right away as it is supposed to (while transcribing and allowing me to answer if I choose) or it may show up hours or even days later. I have tried everything up to resetting the entire phone. I’ve spent hours on the phone with AT&T to get nowhere. This has to be an issue with the iOS. The blame trying to be placed on the carriers with ALL of the carriers having the exact same issue, leads me to believe this is a problem in the iOS. I’m reading threads going back a few years about people having this problem and no fixes have come for it yet.

I'm seeing similar.

No voicemail notification, but if I go to the Phone app, and tap Voicemail, all of a sudden it is there.

Today I noticed I'd had a missed call yesterday (16 hours ago), but not the usual follow up text that Telstra (Australia) sends saying "you had a missed call but they didn't leave a message". Weird I thought, no voicemail, and no missed call text.

So I open the voicemail app, where a previous voicemail message is still open. Click the back button to go to the main voicemail screen, all of a sudden, bing bing, you've just received a voicemail. It was from 16 hours ago.

I'll add that this started happening when i got my new iPhone 15. Same carrier, new phone.

Voicemail messages are delayed by 30 hours ! This causes a major problem when doctors or my 88 year old mother can’t reach me with an urgent message ! And sorry, I don’t pick up the phone for every spam call ! That’s why I have voice mail ! It’s useless to share this on the forum, we all should call apple tech to complain en-mass !!!! This can mean the difference between life and death for many of us !

I have AT&T and my voicemails are ALWAYS delayed, sometimes by as much as several hours. I just now received a VM at 5:30 pm that was left at 1:00. Running iOS 17 on iPhone 15 pro, but I’ve had the issue as far back as iPhone 11. If it’s not a bug in the OS, I’ll eat my hat. Otherwise all carriers s**k and need to get with the program.

I just purchased an IPhone 15 Pro and I am not receiving VMs until a day later! What to do?

For what it's worth, I'm on T-Mobile and have experienced this problem intermittently for years. Since I don't use voicemail that much, I haven't logged when and where. But this week, I saw my dentist made a call on Wednesday, and didn't leave a voicemail. The voicemail appeared today, Friday.

It is unconscionable that Apple has not fixed this problem. For those of us who rely on our iPhone for business… missing calls and receiving messages days later causes serious credibility issues. Come on Apple… stand up to the problem, stop blaming carriers and fix it.

Please contact your Carrier as VoiceMail is a carrier-specific feature --> Check your voicemail on iPhone - Apple Support

You may try some of these steps, please check after each step...

The delayed Voice Mail message typically indicates an issue with the settings on your iPhone. There are several potential reasons for this error, and here are some troubleshooting steps you can follow to resolve the problem:

1. Ensure that your iPhone has a stable internet or cellular connection. Voicemail services may require a data connection to function correctly.
2. Check if there are any carrier settings updates available for your iPhone. Carrier updates can sometimes resolve voicemail-related issues.
3. Contact your carrier's customer support to ensure there are no known issues with their voicemail services in your area.
4. If you have call forwarding enabled, try disabling it to see if it resolves the voicemail problem. Go to Settings > Phone > Call Forwarding and turn it off if it's enabled.
5. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
6. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
7. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
