Swapped to eSim on my new iPhone 16 Pro Max, I get a constant voicemail notification

@chrisgramst ​@o2_Giulia How was this fixed? I am facing this issue as well. But the o2 prepaid customer care wont talk to me in English, so unable to discuss this with them.

Hi ​@heisenberg1602 

welcome to our community. Nice to meet you. 🙂

What exactly is the problem? Do you have a red dot on your screen as a notification? Or anything else?

Hi ​@o2_Manga, nice to meet to you as well :)

You wrote it right - there is a constant red dot on the screen (Phone app) as a notification. Won’t go away no matter what. I have no new voicemail either. 

Hi ​@o2_Manga thanks for your help! The activation of visual voicemail, and then a phone restart worked! Thanks again - this is such a relief :)

That is great that the voicemail notification is no longer shown on your new iPhone 16 Pro Max, thank you for your feedback, ​@heisenberg1602 🙂

Best Regards,

Gerrit

​@o2_Manga ​@o2_Gerrit it is back again. the red dot on your screen as a notification came up again. I missed a call last night and it just came back :(
I checked for any new voicemail, but there is none.

Can you please do your magic again and fix it?

Dear ​@o2_Manga ​@o2_Gerrit (maybe you missed my previous comment!)

Hello ​@heisenberg1602,

can you try to activate the visual voicemail vie calling 331, then choose 9 and afterwards 8 to change the settings for viisual voicemai?

Then you can activate in order for the red notification dot to disappear.

Best Regards,

Gerrit

Hi ​@o2_Gerrit , thanks for your message. Sorry to say, I already have tried this in the past - but it doesn’t work. when ​@o2_Manga did it, the issue was solved instantly. Can we please do it again?

​@heisenberg1602 I did activate visual voicemail for your number, you will receive a confirmation by SMS 🙂

Regards,

Gerrit

​@o2_Gerrit Thanks but it didn’t work this time, unfortunately. Is there some other way to do it? Maybe walk into a o2 store? What do you suggest?

​@heisenberg1602 

could you please retry the steps? The voicemail was still deactivated, I hope this is not a deeper problem. 

Greetings

​@o2_Manga unfortunately, nothing helps here. It’s still there after trying all the steps you mentioned earlier :(

Hello ​@heisenberg1602,

I apologize for our later answer, your thread seems to have slipped under the radar.

Do you still have the constant voicemail notification on your phone?

Only currently you are registered here in our o2 Community via a Prepaid number, for which visual voicemail is not available and cannot be changed by us.

Best Regards,

Gerrit
