How to change voicemail number
My Voicemail is not working. I see the red notification dot in the phone app but when I press call voicemail it will not connect. I can call the voicemail manually (in my case 443 for giffgaff voicemail)
How can I check and reset the number that the phone app is calling?
NB this is NOT a question about visual voicemail. It is not available on my network.
The voicemail used to work fine but after adding an esim it has stopped working so I suspect the voicemail number got changed.
I just want to set the number back to 443. I’m pretty sure on older iphones there was a setting somewhere for ‘voicemail number’ but not any more it seems…
