Intermittent problems making or receiving calls

[Megmeghello]

Hello I updated my phone to the iphone 16 pro just over a month ago and have been having problems making and receiving calls this last week but only on the occasion.

Most of the time my calls will go through with no issues and then occasionally I will get a call and not realise until I receive a message saying I have a voicemail or a message from the person contacting me to ask why I haven’t answered. I never receive a notification for the missed call and find I can’t call them back when I try.
There is no error message no dial tone nothing and I will have signal the whole time. I can use data/wifi fine to facetime them back and can still receive messages.
I have turned off live voicemail but that hasn’t improved and there is sometimes a long delay between dialling and connecting. I am worried because if I need to make a call in an emergency and this happens at the time I will be completely vulnerable.

Hi,

I’m also suffering from this very same issue that others are having. Today was the latest of suffering from the issue, and only knew again when I received a WhatsApp message asking why their call was going straight to my voicemail. I tried to call them back but was unable to do so, no dial tone, nothing! I had to put my phone in to flight mode several times for it to start working again. 
The frequency of this occurrence appears to becoming more frequent.

This issue only started after your major outage in January. I had never had this issue until then but now is becoming a weekly issue. 

I am on the verge now of moving my phone contract to another network provider.

Hi @JohnnyDT,

I'm really sorry to hear about the disruption this issue has been causing you. Can I check is this an issue when you're out and about or at home using Wi-Fi calling? Are you using an iPhone?

Thanks,
Jonathan

Exact same issue here

- incoming calls go straight to voice mail without ringing, but I can't call Voice mail because cant make any out bound calls, they jsut never connect.

Hey @ClaytsUK 

Welcome to the Three Community Page.

Sorry to hear that you're having this issue with making and receiving calls.

How long has this been going on? Can you confirm which phone you are using? Can you also confirm if you're always having the issue, like when you're out and about, or if it's specific to when you're home? Have you tried a reset of your network settings?

Hi there

My phone has been doing this for several months now 😡 It’s intermittent and happens when I’m connected to Wi-Fi. And found out this is also happen to close friends of mine, who are also with Three ! People have been ringing me , and getting an automated (Not my pre-recorded) message and sent to my mail box. And I’m getting a very strange method/way of having to try and access these messages (not through the normal way) And I can’t ring out… I then need to disconnect from the Wi-Fi switch to airplane mode for 10seconds , then call whilst still disconnected from Wi-Fi. This is not a Wi-Fi issue , this is to do with Three. Like I stated earlier , a close friend and her daughter (both with three) are having the same issues, which have been going on a good while. So please sort this out…

Hi Mark,

That's really odd that you've mentioned your Voicemail being different when this happens, do you mean Live Voicemail, as described in this article: Introducing Live Voicemail 

You mentioned the issue is intermittent, so it's not every time that you're connected to Wi-Fi, but you have been any time that you've noticed that you're missing calls?

Thanks,
Jonathan

Is no one from three looking into this issue now? Or are all your heads still buried in the sand… I’ve resorted to turning my Wifi off when I’m not using to stop this problem… It’s a damn nuisance tbh…
