WiFi 7 capable
iPhone 16 model phones all support WiFi 7 (802.11be) with 2x2 MIMO (Multiple In, Multiple Out) antennas.
The WiFi 7 standard builds on advancements made by WiFi 6E, by enabling higher speeds and lower latency, operating in the 6GHz band, so performance continues to get faster.

Enabling VoLTE
VoLTE is available on the One NZ network, right across New Zealand, including the RBI2 cell towers. VoLTE works on iPhone 6 and all newer models of iPhone. You'll want VoLTE simply for the sound quality on phone calls, and there are more benefits with VoLTE. You can learn more about VoLTE here.
