Visual voicemail keeps going off, and phone forwarding icon keeps appearing

[Anonymous]

Hi

I am on a monthly pay 4G package with O2 with my iphone 5S.

EVery two or three days, visual voicemail switches off saying there is an error with visual voicemail. When this happens, voicemails are left for me, but the caller does not hear my personalised OGM and I have to call in to listen to voicemails - and I get no notification of new voicemails. If I power down my iphone and switch it back on, visual voicemail is restored. But then a day or two later, it all happens again 

Another thing I have noticed, is that when I switch my iphone back on after having powered it down, the call forward icon appears on the phone, even though I have not set call forwarding. To celar this I go into settings - phone - call forwarding. this shows that call forwardins is indeed off, and as soon as i reach that screen in settings, the call forwarding icon goes away - and so does my 4G connection. I then have 3G connection for a while and then magically 4G returns after several minutes.

Thsi is all comepletely repeatable - happens every time

Yesterday I noticed that exactly the same things are happening on my wife's iphone 5 - and she is on an EE package

What is going on?

I used to get the call forwarding icon on my iPhone 4s long before 4g the advice in that thread should help

Thanks adamtemp64

That worked and seems to have cured the call forwarding icon appearing when it shodul not

Thank you. The key thing to do in those instructions is to swith on call forwarding temporarily, and put 901 in as the number to forward calls too (this box was empty on my phone) and then switch OFF call forwarding again. That cured it

I do not know if this will have any impact on the problem with the visual voicemail - I will have to wait and see if that problem re-occurs
