How It Works

1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
Get stronger signal

Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.Installation

- What is a mobile signal booster? - A mobile signal booster is a device that helps improve weak mobile phone signals. It takes the existing signal from outside, amplifies it, and then sends it inside your home or business. This is especially useful in areas where the mobile network signal is weak, allowing you to make calls and send texts more easily.
- How does the 250m2 Telkom Mobile Signal Booster work? - The 250m2 Telkom Mobile Signal Booster works by capturing the 1800MHz frequency used by Telkom in South Africa. It boosts the signal for voice calls and text messages, helping to provide coverage in areas up to 250 square meters. This means you can connect better in homes, cafes, and other medium-sized spaces.
- Can I install the booster myself? - Yes, you can install the booster yourself! The kit comes with everything you need, including the antennas and cables. We recommend starting with a loose installation first, so you can find the best spots for the antennas before making everything permanent.
- Where should I place the outdoor antenna? - The outdoor antenna should be placed where there is a good mobile signal, usually on the roof. This will help it pick up the best signal possible to amplify inside your home or business.
- Will this booster work if there is no signal outside? - No, the booster cannot create a signal; it can only amplify an existing one. If there is no mobile signal outside, the booster won’t work for you. You need some signal to start with.
- Can multiple people use the booster at the same time? - Yes! The 250m2 Telkom Mobile Signal Booster can support up to 25 users simultaneously. So, you and your family or friends can all enjoy better reception at the same time.
- What happens if my external cable is not long enough? - If the standard 10-meter external cable is not long enough for your setup, you can upgrade to a longer one. Options include 20 meters, 30 meters, 40 meters, and even 50 meters, ensuring you have enough length to connect everything properly.
- What is the advantage of upgrading to a higher gain aerial? - Upgrading to a higher gain aerial can improve the performance of the booster, especially if you're indoors and only getting 1 or 2 signal bars. It helps capture a clearer signal from outside, leading to better call quality.
- How can I check if my phone is on the right frequency band? - You can check your phone's frequency band by dialing *3001#12345#* and pressing the Call button. Look for 'Freq Band Indicator’ under 'Serving Cell Info' to see your current frequency.
- What should I do if I have trouble installing the booster? - If you have trouble installing the booster, don’t hesitate to contact customer support for help. They can guide you through the installation process to ensure everything works well.
