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
- Connect the indoor antenna to the MS port.
- Connect the outdoor antenna to the BS Port.
- Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
- Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
- Power on the booster and check the signal strength.
- Adjust the outdoor antenna until you get the best signal strength.
IMPORTANT NOTE:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

- Which mobile networks are compatible with this booster? - This signal booster works with various networks like O2, Telekom, Orange, FunFon, Swan 4ka, Tesco Mobile, and Juro. It can improve 2G, 3G, and 4G signals, helping everyone in the household, who may be on different networks, to get better reception.
- How much area can the booster cover? - The mobile signal booster can cover an indoor area of up to 500 square meters. This makes it ideal for medium-sized homes, offices, warehouses, and more, allowing multiple users to enjoy enhanced mobile signal at the same time.
- Can I make voice calls using 4G with this booster? - Yes! If your phone supports 4G Calling, also known as Voice over LTE (VoLTE), and you have 4G coverage, the booster will help you make clearer voice calls. If there's no 4G network in your area, you can still use 3G for calls and texts.
- What do I do if I have no signal outside? - If there's no mobile signal available outside, the booster won't work. It can only amplify the existing signal. So, it's essential to check the signal strength in your area before purchasing the booster.
- Is it easy to install the signal booster? - Yes! The signal booster kit includes everything you need for installation. It comes with an external aerial, cables, and a power adapter. You can easily install it yourself by following the provided instructions.
- How many users can connect to the booster at the same time? - The signal booster can support up to 50 users simultaneously. This means many family members or coworkers can enjoy improved signals for calls and internet usage without interference.
- What is the frequency range that this booster operates on? - The mobile signal booster operates on three frequency bands: 900MHz, 1800MHz, and 2100MHz. This allows it to enhance signals across various mobile networks that operate on these frequencies.
- What additional accessories are available for the booster? - To improve performance, you can upgrade your installation with longer external cables, a higher gain antenna for better reception, or a surge protector to safeguard the equipment from electrical surges due to lightning.
- Can the booster improve my phone's battery life? - Yes! By providing a stronger and more stable signal, the booster helps reduce the effort your phone has to use to maintain a connection. This can lead to longer battery life, as your phone won’t drain its battery as quickly.
