Boost Your Mobile Signal Today

Introducing Cel-Fi, the simple and legal answer to boosting a 3G/4G signal in your home, office or vehicle.

Cel-Fi PRO for Homes/Offices

Cel-Fi PRO has been specifically designed for homes and offices as an easy plug and play device that will get your 3G/4G mobile signal working - in just 5 minutes. It will eliminate dropped or missed calls, increase mobile data speed, extend mobile battery life and improve voice quality.

There is a Cel-Fi PRO model for each carrier, Telstra, Optus, and Vodafone plus other operators on their networks including Aldi, Boost, Virgin, iiNet, Amyasim, TPG and iPrimus.

Cel-Fi GO for Cars/ Boats/ Caravans / Trucks

Cel-Fi GO for Telstra is your solution when on the move. It provides up to 100dB gain - that's over 30x more powerful than a standard antenna and car cradle set-up. No longer will you need to stop or drive to a particular spot to make and take calls. Cel-Fi GO can improve coverage for all types of vehicles from cars to trucks, farm machinery, boats and caravans.  Cel-Fi GO models for Optus and Vodafone are currently in development.


Improves Mobile Coverage

Simply install Cel-Fi inside your home, office or vehicle and enjoy having great 3G and 4G coverage.


Eliminates Missed


Never miss or lose an important business call again because of coverage issues.


Increases Data


Slow internet speeds on your mobile are often caused by low signal. Amplify your signal .. and speeds increase.


Extends Phone Battery

Phones utilise more energy in low coverage areas, using more power to compensate for poor signal. Your battery should last noticeably longer with Cel-Fi boosting signal.


Improves Voice Quality

With improved signal strength, Cel-Fi will provide crystal clear voice quality for your phones.


Simultaneous Users

Cel-Fi products will provide a coverage area sufficient for multiple simultaneous users, up to 20 depending on activity.

With a bluestone office, my phone reception is terrible where I need it most - even though the Telstra tower is only 2km away. Also, the mobile broadband backup unit gets no reception at all in the office. Installed Cel-Fi PRO with one unit nearest the Telstra tower, the other in the office, within a minute I had 5 bars on the phone. Get full 4GX on the mobile broadband unit too. Nothing to configure, true plug-and-play. Excellent gadget, and the associated app is great too..“
