iOS 7 - Voicemail not working

[Anonymous]

Since upgrading to iOS7 my iPhone 5's voicemail system has ceased to function.  The O2 Gurus were no help whatsoever and the customer service line is 'busy'.  Anyone else had the same problem?

I had the same issues and the old 'switch it off then back on again' worked for me. After restarting the phone, all was well.

Reset network settings worked for me.

Settings>general>reset>reset network settings,

Phone reboots and visual voicemail returned

Had similar problems after 2 days trying to resolve my voicemail, either just cutting straight in and no phone ring to the opposite just ring out and no voice mail. I was told turn on voicemail in the TU go App and it works, but it begs the question regards the App for sure

Had this problem on my wife's 5S, (TU GO app not installed) and turning WiFi off and on fixed the issue.

I've had issues with Visual Voicemail for several months - hangs and restarts of the phone app when trying to delete or listen to messages.

I've even resorted to a factory reset and fresh set up (to ensure no bad settings carried across from old back ups) to try and resolve the issue, but this didn't help.

However switching off Wifi then deleting the voicemails seems to have worked...

3 beeps is all tha you will hear. Same for 1750 to turn voice mail back on. This fixed my problem of no voice mail when mi iPone 4 was switched off.

For anyone joining this thread and getting the 3 beeps for voicemail 176002 to turn off and 175002 to turn on. this seems to work if you have TU Go installed.

Tried all these tips after the visual voicemail on my iPhone 4 (IOS 7) stopping working since changing networks back to O2 recently.  I believe it worked once after resetting the network settings then stopping working again, requiring me to dial 901 to access my voicemail messages.

It turns out the problem might have been because I had not synchronised with iTunes since changing provider.  One of the O2 Gurus prompted me to check this while activating the service on my contract again, although he may have just done the same from his end as me dialling 1760 to deactivate the service then 1750 to reactivate it again.

In short, make sure you have synchronised with iTunes recently, especially if your on a new contract as it might sort the issue for you as well, although perhaps ask O2 to check it is enabled on your contract as well.

I've tried everything listed here. Most recently reset my phone entirely and reconnected with itunes but still to no avail. 

Are there any updates please?
