Error when trying to retrieve voicemails on iPhone

This Error has become exhausting. Whenever I try to click on greeting, I’m immediately greeted with “The operation couldn’t be completed. (com.apple.mobilephone error 1034.)”. This have become compounded with my discovery that not all voicemails are populating in the voicemail tab. I’ve had to dial out to voicemail to hear them.

Phone Details:

IPhone 15 Pro Max
iOS 17.6.1
T-Mobile carrier

Additionally, here are the steps I’ve tried:

Reboot phone
Delete T-Mobile Scam Shield App
Ensure no VPN’s are running
Reset Network Settings
Reset All Settings
Erase all content and settings, then restore from iCloud Backup
Erase all content and settings, then set up as new
Erase all content and settings, including ESim, then set both up new.

Nothing seems to be working. This is exhausting as I need to get voicemails as a parent. There needs to be a fix for this issue. Any further thoughts?

You must have a cellular network connection and cellular data turned on for visual voicemail to work. That error code is a carrier error, so if you have cellular data turned on contact your carrier for support.

I’m not so quick to blame the carrier on this either. Because many different phones on many different carriers are experiencing the same issue. I did all the steps Lawrence suggested and that didn’t help. T Mobile did mention they’re working with Apple on a broader fix since so many have this issue, but I’m betting the other carriers are working on the same exercise.

Interesting … my friend and I are both with O2 here in the UK. His iPhone is still on iOS 17 and he doesn’t get a text transcript of voicemail messages, also the default voicemail greeting is a woman welcoming you to thje O2 messaging service, as it always has been. He doesn’t get Error 1034 either and can record a custom greeting.

My iPhone has been updated to iOS18 (now 18.01) and has the Error 1034 preventing any customisation of the Voicemail Greeting. Also, I receive a text message transcription of messages left AND the greeting is now a man’s voice saying that the call is being diverted to the messaging service.

So it would appear to be linked to this change of the messaging service that my phone now has compared to my friends 🤔

I'm having exact same issue, but I'm with Verizon, not T-mobile. I have gone through two different Iphone 13's and now on a Iphone 15. So I'm thinking it is NOT an Apple thing, unless it's a previous IOS software update that threw this into a tailspin. I also have the same issue, being some voicemails go into the voicemail phone app, others have to be plucked out of *86 (Verizon's method to retrieve voicemails). So it's like I have two separate voicemail boxes, neither of which sync with each other. Been battling this for over FIVE MONTHS. Have been escalated multiple times to Verizon's senior tech level. They try this, they try that, then it works for a few days...then back to the same issue. And so yes, this IS exhausting. Every call with Verizon is at least 90 minutes. Getting old. If anyone has any updates, would be most grateful to see what you have done! Interestingly, I have not heard of anyone on a Samsung having this issue. Have any of you heard that from anyone???

I checked Cellular data and that’s fine. Additionally, I contacted both Apple and T-Mobile. T-Mobile sent it to the engineering team who’s working on it; Apple wasn’t quite as helpful. Also, another phone on my account is not having this issue.

Just an update that I have my new 16 Pro Max and this still exists. Searching forums and this seems to be happening on other carriers as well. I’m hoping at some point this somehow gets fixed. I’m open to any other suggestions.

Oct 11, 2024 7:06 PM in response to Lawrence Finch

Thanks Lawrence. Interesting information. My lingering question is though, why does it have the word "Apple" in it? Does that mean on a Samsung, the "Apple" will be replaced with "Samsung"? I don't know. Haven't had any interaction or responses from Samsung users to see if they are having similar issues. I'm working with "executive level" Verizon reps, trying to figure it out. Wondering if I was to try a Galaxy, would it replicate the issue????

I’ll have to try this. When exactly did you do the hard reset? While the Apple logo was on screen during the network settings reset, or as soon as the phone booted up post reset? At this point I’ll try anything.

I have an iPhone 11 iOS18.01 with O2 as well in the UK. The problem occurred when I changed my tariff, whereupon up came the 1034 message and I can’t re-install my voicemail message list. I can manage ringing voicemail but it’s annoying.

If anyone is still reading this, I can report that having successfully resolved the 1034 issue with my carrier, it lurched back to its former state, only to recover without my having to revisit O2. I mention this just illustrate what seems to be a random fault.

Sep 21, 2024 10:27 PM in response to auriconis

Was this ever resolved. I’m having same 1034 error and endless spinning trying to play Greeting or Custom greeting.

Not as of yet. I keep hoping the next update will fix it but so far nothing. Do you have TMobile as well? Just so I can compare.
