Visual Voicemail doesn't work when using Wi-Fi Calling

CorrectHorseBat — Thu, 01 Sep 2022 09:53:27 GMT

I have an iPhone 12 Pro and have Wi-Fi Calling and Visual Voicemail.

When using Wi-Fi Calling, Visual Voicemail doesn't work. New voicemails do not come through to my phone until I have mobile data again.

This seems like a major oversight, @O2Sarah- please advise?

@CorrectHorseBat

You need mobile data to be working to get the notifications it is a well known limitation to Visual Voicemail...

Nothing to do with o2, just a by design in the GSM standards.

VVM has always needed a mobile data connection to work.

It's not a limitation of wifi calling.

Then you need to contact O2. As this is a community forum and everyone here are customers just like you.

I totally agree with you @MI5

@CorrectHorseBat

o2's contact number is 202 from your o2 phone or 0344 809 0202 from another phone...

Good Luck, as you will get the same answers from them...

And on the point of Three and VVM, this page explains there VVM service

https://www.doesthreesupportvisualvoicemailyet.com/

And EE you need Mobile Data to access VVM

Trust me I know, with over a 1000 devices I manage across multiple UK and Global networks... but then again what do I know...

I just tested it on my EE SIM AGAIN and it worked.

@O2Sarah- hope you will be able to explain why O2 does not support this.

Hi @CorrectHorseBat . I can confirm that with o2 you do need an active mobile data connection for visual voicemail to work. You can still access voicemail by calling 901 if you need to while mobile data is not available. I understand this is different to your experience on EE but I can only comment on the support available on o2.

Thanks

Thanks, please submit this as feedback to be improved/changed so you can use Visual Voicemail without mobile data as this is something other networks support. Many thanks.

Well the good news is that O2 finally does support Visual Voicemail over Wi-Fi Calling!
