I thought it might be a good idea to start a thread where people can discuss any calling issues they’ve been having since the 2G/3G shutdown.
For example, the other day on my iPhone XS Max I tried calling someone and it just sat on “Calling…” with complete silence — no ringing tone, nothing — and it never progressed to a connected call. I hung up and tried again with the same result. I then tried toggling Airplane Mode on/off, but it still wouldn’t work.
I tried calling a different person and got the same issue, so I ended up using Viber to make the call instead (although Wi-Fi Calling probably would have worked too).
Interestingly, after the Viber call finished, normal calling started working again.
I’ve also noticed that sometimes when calling someone there’s no ringing sound at all — just silence — and then suddenly the person answers and the call proceeds normally.
About a month ago I also received a “Who Called” text saying I had missed a call, even though my phone was on the whole time and never rang. When I called the person back, they said it did ring from their end.
Is anyone else experiencing strange calling behaviour now that the network is relying entirely on VoLTE/IMS?
It’s been around two months since the shutdown, so I’m surprised some of these issues still seem to be happening.
For context, all of these issues occurred on the cellular network with Wi-Fi disabled, so this was standard VoLTE calling rather than Wi-Fi Calling. My signal strength in my area is generally good.
I’m also interested in gathering other users’ experiences before potentially logging a fault with One NZ, to help determine whether this is a broader network/IMS issue or something localised.
