why doesn't visual voicemail work after upgrading to ios 7?

Might want to check with Verizon. Something about the update may have messed up things on their end. They may have to reset your voicemail.

I have the same issue with my iPhone 4 and german T-Mobile. After updating to iOS 7 my mailbox does not work for callers, just tells them I did not answer the call, and visual voicemail on my phone is not working and just calls the standard voicemail.

I tried to set a new password for visual voicemail in the phone settings (as supposed to do in some forums), but this just hangs after entering the new pin twice.

I changed the settings in the mailbox menu, so callers can record a message on my mailbox again, but visual voicemail still is not reactivated.

As mentioned earlier, check with the carrier. Voicemail is a carrier function. They can control it, reset it, and disable it.

Reset network settings worked for me.

Settings>general>reset>reset network settings,

Phone reboots and visual voicemail returned

Ok, I reactivate visual voicemail with the help of my carrier (note for other visitors from germany using T-Mobile: send an SMS with content VVM to 3011 and visual voicemail will work again), but I do not understand why a software update on my phone will lead to a not functional visual voicemail on the carriers server. Did the communication protocol change?

I got the same response from VZW as well. It seems like these companies are playing the "blame game". I tried all of the suggestions to fix VVM, but nothing worked.

Thank you this worked on t-mobile with an iphone 5 on ios7.

Most likely a phone problem, apple just not taking responsibility seeing as it worked prior to the update the only thing that changed was the ios software. How can you blame a carrier for a problem that only started after a software update? :rollseye:

I know it is not the carrier. It is a problem with the software. Voicemail continues to work. The problem is with the voicemail software. I can't even use the edit button there or highlight a message. And if it was the carrier then why did it work fine before upgrading to ios7?

Thank you for the simple fix. A new problem for me is that after the fix now I'm only seeing "4G" in the top network indicator (next to "T-Mobile"). Before the fix I was seeing T-Mobile LTE (their faster network). When I went to: Settings / Cellular / Cellular Data Network -- the LTE Setup (optional) fields are blank. Don't know what this means. Have I lost the LTE faster network feature? Will have to go to T-Mobile...but now my visual voicemail works...yaaaay

Current settings for tmobile i have are:

Cellular data

Apn:fast.t-mobile.com

MMS

Apn: fast.t-mobile.com

Mmsc: http://mms.msg.eng.t-mobile.com/mms/wapenc

Mms max msg size: 1048576

My vm works and shows LTE at top. These settings were populated automatically for me.

Update on T-Mobile LTE disappearing and going to T-Mobile 4G after ioS7 upgrade and checking the cellular data settings: I am getting the T-Mobile LTE in the network indicator now randomly, so I won't be rushing over to T-Mobile, but before the update it always stayed on T-Mobile LTE. My T-Mobile Cellular Data settings are the same as Ryan's.

Thanks

I did a soft reset to my phone and it resolved the issue. Hold down top button and home button until phone shuts off and keep holding them till the Apple logo appears at reboot. This doesn't erase anything and is always the first thing I try when I have a problem.
