Phone Boosters

Stay in contact when you leave the city behind with a mobile phone signal booster. Boosters amplify weak signal from distant towers, helping your phone hold calls and data in fringe coverage areas across regional Australia.

We stock Cel-Fi GO boosters with options for the Telstra and Optus networks, plus the Cel-Fi ROAM R41 coverage solution. Buy online with Australia-wide shipping, or have your booster supplied and fitted at our Burwood workshop.

Choosing a phone booster

The first decision is network. Cel-Fi GO boosters are configured for a specific carrier, so choose the Telstra or Optus version that matches the SIM you travel with, and think about which network has towers along the routes you actually drive.

Antenna choice and mounting also make a real difference, since the external antenna is what pulls in the weak signal for the booster to amplify. The Cel-Fi units we stock are paired with quality RFI antennas, and the Cel-Fi ROAM R41 offers a packaged mobile coverage solution. A booster helps most in fringe areas, though no booster can create signal where none exists.

Phone booster FAQs

Will a booster work if there is no signal at all?

No. Boosters amplify existing signal, so they shine in weak or patchy coverage rather than true dead zones. If you regularly travel beyond mobile coverage entirely, pair a booster with a UHF radio or satellite communicator for safety.

Do I choose a Telstra or Optus booster?

Match the booster to the network your SIM runs on, and think about which carrier covers the regions you travel most. If you are unsure, call our Burwood team on 03 9808 8966 and we will help you decide.

Can Complete 4x4 fit a phone booster to my vehicle?

Yes. Our Burwood workshop fits boosters and antennas with tidy cable routing and sensible antenna placement. We can also ship your booster Australia-wide if you would rather install it yourself.
