PoHq:

Trying to test mine at the moment. Latest iPhone iOS 15. All enabled in options, I turn on airplane mode and enable wifi, I see Voda NZ Wifi but when I try and make a call it says no network available turn off airplane mode.

Airplane mode + VoWiFi seems to work (tested to voicemail) on Android. Maybe an iOS implementation? Have you made a VoWiFi call while airplane mode is off (just wondering if there's some 'activation' involved)?

Got it working. It was a dual sim issue, my spark sim was set to default voice line so when it was in airplane mode it was trying to use that. I set default line to voda and it worked. Interestingly I put my default line back to spark as I want it like that and wifi calling worked. It all works in airplane mode as it it should. As long as you see vodafone wifi whilst in airplane mode you are good.

Calls seem pretty good.

Probably needs access to the SIM card for authentication, which is disabled in aeroplane mode.

Nope, wifi calling works for me with aeroplane mode on.

Both WiFi Calling and VoLTE enabled on my dual-SIM S21 for both 2degrees and Vodafone. Well done to those behind the scenes making this happen! :)

The dream! Is it running the firmware variant of one of those telcos?

Okay so a few quick questions/Summarisations:

Geographical limitations with VoWiFi
- Only accessible in NZ or can this now be used as a roaming alternative?
- If no, will a VPN work?
Vodafone VoWiFi can hand over to VoLTE
- What about handover to 3G/2G
- What about network handover to WiFi?
- Expect handover delay to be up to half a second
Only certain phones that Vodafone approves will get access to VoWiFi
- If you use a Vodafone MVNO such as Kogan, they appear to have less restrictions on limiting phones
Currently official support is limited to:
- Samsung S21 series
- iPhone devices > iPhone 6S/SE or newer devices
- More will come over the coming months
Sure signal will stop on 10th Dec'21
- Sure signal users will receive text messages asking them to purchase a compatible device (currently an S21 or iPhone device) to prevent loss of service
User Experience
- Currently some users are reporting teething problems including call drop outs when using VoWiFi.
- VoWiFi will work when the phone is on flight mode under most circumstances. However users with dual sim functionality may need to play with their SIM selection settings

Anything else?

I believe that Samsung supplies a single NZ firmware for all NZ telcos for the S21. So same firmware should work fine with all the NZ telcos.

Thanks. I'm currently using a Vodafone primary connection and a 2degrees secondary connection on a non VoLTE and non WiFi Calling capable handset. Samsung seems my best bet for gaining these 2 new calling options on both providers. Or an iPhone. Anything else?

I've done some further non-work testing on Wireless Calling, seems to be holding calls up a lot better than yesterday.

I look forward to the day that I can retire the basement/mancave/garage suresignal :) Will give it a second go on work related calls tomorrow.

Thanks in advance to all the people testing which phones will work best with VoWifi, so that I know which one I should buy come December. 😀

@Linux, exactly, I dont need to race out and buy one now.

I can read everyones reviews here and make a considered purchase closer to the time.

I am not expecting my Xiaomi MiMix3 to be on the list, ever.

If it helps you with your decision making, many of the former Geekzone IRC moderators were secret iPhone fans (Nate and Brad), including the big man himself. ;)
