Right across Australia, navigating through patchy mobile signal coverage can be a challenge due to terrain or interference. CEL-FI GO mobile cellular signal boosters by NEXTIVITY are the only products approved and supported by the Telco Carriers and ACMA as they provide a reliable solution tailored to various needs with their range of models. These cellular boosters amplify signals effectively, yet it's worth noting they need at least one bar of reception to work optimally. Whether it's calls or data, Cel-Fi ensures seamless connectivity across major networks like Telstra, Optus, and Vodafone, ensuring you stay connected when it matters most.

There are no monthly fees or ongoing charges like STARLINK, making it a cost-effective choice for improving your mobile experience.

R41 Cel-Fi GO devices are best suited for roaming in-vehicle applications as the device can automatically connect to the next tower as you approach the area. G41 and G51 CEL-FI GO devices are designed for stationary fixed site applications providing a powerful signal output for multiple internal ceiling wall antenna setups to cover any given building or house. G51 supports 5G mid-band which is commonly found in major urban centres and large cities.

Regional and rural areas generally have 4G and the soon to be discontinued 3G which may see some of it's bands repurposed to 5G NR low band.

CEL-FI GO STATIONARY Cellular Signal Repeaters

STANDALONE CEL-FI GO Signal Booster Devices

3G 4G 5G* Mobile Signal Cellular Antennas


5G Telstra Update: Telstra has completed 5G tests using their repurposed 3G bandwidth frequencies within their network allowing 5G to operate in the low-band 850MHz spectrum. This will no doubt increase 5G Telstra coverage in areas across Australia making the 5G network accessible for more people. 

Please note that 5G high-band frequencies are rarely available in remote areas where a CEL-FI GO is commonly used. The 4G network will still be the backbone of cellular data and communications in Australia for the foreseeable future even when the 3G network is eventually switched off by the end of 2024.

  • 5G Low Bands - Under 1GHz (Telstra 850MHz)


    • Rural & Regional Areas

  • 5G Mid Bands - 1 GHz to 6 GHz (Telstra 3.5 & 3.6GHz) *Most Common 5G Consumer Band*


    • Major Cities & Urban Areas

  • 5G High Bands - 24 GHz to 40 GHz

Buy with full confidence knowing that the G31 CEL-FI GO will still be relevant for many years to come as Australia's regional areas utilize the 4G and 5G NR Low Band network!
