SOLVED Voicemails not showing up until days after they were left

Great that you found this fix. Sadly it didn't work for me. I have no visual voicemails and only 2 regular voicemails. Still voicemails can take up to a day to show up:(

This is an issue for me as well. Important messages take anywhere from a few hours to four days to come through. The veterinary office called regarding an animal that was at their office at that moment. I wasn't able to answer right away, so it went to voicemail. I still haven't received that message and that was hours ago. Thankfully I was able to answer when the vet called a bit ago, but who knows what kind of information was in that message. I tried the "fix" above and it did not work at all. I tried resetting the phone as well and this still happens. This is super frustrating and happens on a regular basis. I didn't have this problem with Sprint. What's going on with T-Mobile? Based on what I see here, this problem has been going on for years and they still haven't fixed it. I'm receiving some good offers from Verizon. Maybe it's time to switch.

Hey T-Mobile, new line. Set up voicemail. But no voicemails are showing up on the phone. People can leave voicemail, but I don't get any notification of voicemail on my iPhone 11. I don't use video messaging, and don't have many texts, so it can't be about no space/storage. Why dont voicemails show up? Read online to say something to you such as "Have them file a Service Complaint under "MWI: Voicemail notifications (MWI) are delayed". Please help!

There is at least a 3 hour delay when receiving voicemails. I just switched to TMobile and IPhone so I don't know which to blame, but I never had this issue before. Please help. Very very frustrating!

Same

Thank you for your post!   I have been struggling also.  So you have to go to your deleted voicemails and delete your deleted voicemails.  Mind blown!  But it worked immediately!

Action1024 do you know if there is a simple way to mass delete messages?  I have tons!

And, once I delete them, is there a trash hidden somewhere I can go to to permanently delete them?

I sure hope this works!  I too have been having the same issue for years!

I have been getting voicemails late from debt collectors but once I receive a regular call from anywhere else, these types of voicemails show up. And it's only them not anyone else. For example, a blood bank called me for a donation today, got the missed call plus the voicemail along with a voicemail yesterday from a debt collector. Idk how legit the scam is because it seems my VM from these kinds are always delayed. Frustrating! 
 

btw - I delete voicemails and texts usually right after I receive them so I have plenty of storage, usually restart my phone once a week, toggled airplane mode, nothing has seemed to help! 

Same issue--this has been going on for years. I don't use visual voicemail and never have more than 5 or 6 voicemails kept on my phone, but if I get notified within an hour or two of a voicemail being left, I consider myself lucky, when the reality is that this is ridiculously bad service. Sometimes I will see that someone has called and I know there's a 99% chance they left a voicemail, but my phone shows that they didn't until an hour, two, three, sometimes days, later. This is ridiculous and WAY PAST TIME TO FIX, T-MOBILE!!

Same issue. I am a small business owner and I have lost business and caused frustration with my clients as a result of getting messages hours or days after they have been left. This has happened on 3 different iPhones. I should leave T-Mobile but my husband has a legacy plan that our entire extended family is on. I have tried everything - even removal of my SIM card. Spent hours trying to address this. Please help. Please. Please. Please.

Same issue here. I just discovered a VM by dialing my number and hearing I had a 6 day old message waiting.  No notifications on the phone, I just luckily (out of the blue) decided to check.   Odd too is when I opened visual voicemail to see if it had the message, the app acted like it was newly installed  (started up with a splash screen advertising a "better" subscription version and then synchronized my messages).   I had used visual voicemail in the past so not sure why it started as if it was just installed.   

I too have been having this problem on and off for at least a year.  Unfortunately I don't think TMobile support reads these messages so don't expect much from complaining here.  Enough people need to call tech support over and over again before they might do something.
