The one and only Cel-fi Go 51 5G cellular repeater approved in Australia by all 3 carriers Telstra, Optus, and Vodafone.

Suitable for Stationary Installation only

The Cel-Fi G51 boasts it can repeat up to 570Mbps download speeds with the right setup and antenna configuration.

Why just have an LTE router that only gives you Wi-Fi when you can have real connectivity for voice calls and data through your standard phone or SIM-enabled device.

There are no fees with the Cel-Fi GO G51. Just register it in your name when you first turn it on, then use it free of charge allowing your phone or SIM-enabled device to handle the standard fees you are already billed. That's right, there are absolutely no fees to use the Cel-Fi GO G51 as it is a cellular repeater that repeats the existing available signal and boosts it up to 100dB allowing improved cellular coverage in areas where there is limited or no coverage.

It's finally here, the Cel-Fi GO G51 5G 3500MHz mobile phone repeater from Nextivity which is fully approved by Telstra, Optus and Vodafone to use in Australia. 

This powerful 5G cellular repeater, which some may call a 5G mobile phone booster is the ONLY approved 5G cellular repeater in Australia* for small to medium consumer/private spaces without requiring cellular carrier authorisation and planning. 

With a massive 27dBm 5G output, 100dB signal gain, and download speed throughput of up to 570Mbps**, this repeater stands tall above it's predecessors and is a cost affordable solution for small to medium business requiring reliable cellular connectivity.


The Australian model of the G51-LE is compatible with Telstra, Optus and Vodafone.

Only 1 provider can be used at any one time which is easily selectable from within the Nextivity Wave app under Settings > Operator. This means that if you ever need to switch phone providers, it is an easy swap of carriers which only takes a couple of minutes.

This option does take a few minutes as it needs to download the new software update from Nextivity servers which requires cellular coverage, or a connection to the Wave portal via ethernet cabling connected to a internet connected switch and a Nextivity Cel-Fi approved installer to connect and initiate the update.
