The Cel-Fi PRO Repeater has been tested, authorised and approved for use on the New Zealand Networks.

Nextivity's third generation Cel-Fi PRO is a cost-effective and intelligent indoor coverage solution for the Vodafone 3G and 4G networks operating on the 3G 900/2100MHz and 4G 1800/2600 bands, or SPark/Skinny 3G 850MHz and 4G 700/1800 bnads. It is designed to dramatically boost indoor voice quality and increase data speeds for HSPA or LTE consumers. Please note the Vodafone unit does not cover the 700MHz 4G band

You will need to use the free Cel-Fi Wave app to register your Cel-Fi for it to work. You can download the app here
