Whichever path you choose, you'll find the perfect booster for your situation in minutes.
Yes, mobile signal boosters work with both 4G and 5G networks in Australia. Our boosters support the frequency bands used by major carriers to improve your signal indoors. Because carriers use different bands for 4G and 5G, a booster compatible with your carrier's bands ensures better coverage for calls, internet, and streaming.
Honestly, it's easier than you think. Mount the outdoor antenna on your roof, balcony, or high on an outside wall where the signal is strongest—aim for at least 2 bars outside. Run the cable inside to the booster unit, connect the indoor antenna, and plug it in. That's it! The booster automatically starts amplifying once powered on.The main challenge is finding the right spot for that outdoor antenna—the stronger the outside signal it captures, the better the booster will spread coverage indoors. Most Aussies complete installation in 30-60 minutes with basic tools, and every kit includes all cables, antennas, and mounting hardware. Check our installation guide for step-by-step instructions if you need help or chat with our support team to help you.
Our mobile signal boosters support multiple devices at once without a fixed limit. The actual number of simultaneous connections depends on the strength of the signal outside your building and the booster's amplification power. Stronger outside signals and higher gain boosters (e.g., 72 dB vs. 65 dB) allow more devices to connect effectively. While there is no strict user limit, data speed is shared among connected devices, so more users may reduce individual speeds.
Absolutely! Whether you’re at home, in the office, out the back of a warehouse, or running a shop with heavy brick or concrete walls, a mobile signal booster can make a real difference. Aussie buildings often have solid walls that muck up your signal by breaking up or blocking those radio waves, leaving you with dodgy reception. A booster grabs the mobile signal from outside, cranks it up, and beams it through your space so you can make calls, send texts, and scroll without dropouts, even in tricky spots where the signal normally goes walkabout.
Nope, a booster cannot create signal out of thin air. It can only take the mobile signal that is already present in your area and make it stronger. If there is absolutely no coverage at all, then a booster will not work for you. In that situation, the key step is to first confirm that you have at least a minimal signal outside, because only then can a booster do its job and improve it indoors.
If everyone in your household or office is on the same carrier, a single-network booster might be all you need. But if you have a mix of users, such as one person on Telstra, another on Optus, and someone else on Vodafone, a multi-network booster is the smarter option. It saves you from having to buy separate units and ensures everyone under the same roof enjoys strong, reliable coverage.
Our mobile signal boosters will improve your coverage without affecting anyone else’s reception. They operate within strict standards to prevent interference, so your neighbors won’t notice you’re using one. Only illegal boosters can cause signal problems for others. Always choose a compliant booster to stay safe and avoid interference.
