This is nothing new for AT&T. Both my wife and I have had this happen with standard voicemail on rare occasion (maybe a couple times each in the last year) with our Sony/Ericsson Z520a's. So unless it's a new reason for it happening, it's neither new nor limited to the iPhone.

While I have not seen days. I rarely get voicemail in a timely fashion. Voicemail generally shows up in my iPhone within an hour or two. It also seems that several voicemails left over a span of up to a few hours show up at the same time.

I have been experiencing the same thing on my new 3Gs. It's maddening and AT&T seems to be oblivious! I've spent well more than an hour of airtime, going from level one to 2 and then into a store. One interesting way to seemingly "encourage" the iphone to cough up the missing voicemail is to perform a soft reboot. Hold the top and bottom buttons down at once past the point where it says "slide to power off." It will reboot and sometimes the voicemails suddenly appear. Isn't this an indication of an iphone problem?

I have been experiencing this, and in the last two weeks it has grown much worse. This morning my phone beeps with a voice mail alert, I look at my phone and two new messages have appeared. I listen and they were recorded more than 24 hours prior. One was important! I was furious... and also happened to be close to an AT&T store. I immediately drove over to lodge my complaint. The customerNOservice rep told me, that this happens, and asked me if I ever turn off my phone. I said no, and she proceeded to tell me how important it was that I turn off my iphone, because she does this with her blackberry! Huh? She was obviously clueless! Or this is just there standard answer.. reboot the phone! I love the iphone and loathe AT&T, sure wish Verizon would get the iphone!

I have noticed this problem occasionally since I bought my iPhone two years ago. However, a recent occurance spurs me to comment here. At about 9:00 a.m., today (July 15), I noticed a new message on my Visual VM dsplay. The time stamp on it was July 11, 10:27 a.m., which is nearly four full days ago!

This is absolutely unacceptable. From browsing the web, it appears that this has been a known issue for some time, which AT&T has not resolved. Wonder when AT&T is going to get sued when a patient dies as a result of an on-call doctor's not being reachable?

This issue with the visual voicemail has created very fustrating situations for me. It has created Work and personal problems for me.

I am a Project Manager and it does not help at all. My wife was starnded at the airport and waited for 6 1/2 hours before i got her voicemail.

sigh.... AT&T get your act together or I am about to drop you after being a 10 year long customer!!!!

Recently, I received 14 voicemails all in one day that were up to two months old. My first call with tech support “added some updates” and told me everything should be fine. Within two days, I found out that I was still not getting all of my voicemail. After multiple calls with tech support I was finally transferred to level 2 tech support. The level 2 person told that the voicemail latency issue was nationwide and was caused by the unexpected sales of the iPhone 3GS. She said that they were updating servers and the problem should be resolved shortly. In the process of all of the technical help, my voicemail stopped working altogether on my iPhone and the final fix was getting a new SIM card. And to be clear, I can now see some of my voicemails on my iPhone, but the latency problem has not been resolved.

I have had the same problem and spoken with Tier I support just now with the same explanation of "wow, never heard of that..." I didn't think to escalate, which I should have done. I have also experienced a different issue. When calling another iPhone user, the user's greeting is actually delayed after the ringing stops, I have documented 5+ seconds of silence before the greeting comes on. Many callers may just give up and hang up with no msg left. Very, very annoying and of course AT&T cust svc has never heard of this issue...

Hi, For about the last month I have had a delay in getting my voicemail messages. Usually about 6 hours or a whole day later. I will see that I have a missed call but assumed they didn't leave a voice mail but then a message will suddenly appear the next day. It is very frustrating to say the least. Thanks for telling about the manual voicemail. I will now start checking each time I have a missed call.

i have a fix for this...go to your iPhone and reset the network setting.

iPhone->settings->General->Reset->Reset Network Settings.

Rebbot your device and you should be good to go.

The visual Voicemail delay is mostly contributed to a jailbroken iPhone or the Tethering/MMS hack.

Enjoy!
