Voice calling over 4G and 5G

Please have a look below to see our supported devices and FAQs.

VoLTE is short for ‘Voice over LTE’, part of mobile high-speed wireless communication standards. That means voice calls will work on 4G and 5G networks.
Until recently, voice calls would connect over 2G and 3G networks, while 4G was typically used for data transmission. Enabling 4G Calling means better connectivity for the mobile network and better capacity.
The One NZ network used by Rocket Mobile will continue to support voice calls over 3G and 2G, for devices that are not 4G capable – and if your call is made outside a 4G coverage area.

VoLTE technology is a core part of the 5G standard, and voice calling will continue to be provided over 4G using VoLTE.
