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.

- What is a Tri-Band Mobile Signal Booster? - A Tri-Band Mobile Signal Booster is a device that helps improve the mobile signal for calls and internet on three different frequency bands: 900MHz, 1800MHz, and 2100MHz. This means it can boost signals for many mobile networks, improving both voice calls and 4G internet speeds.
- How does the signal booster work? - The signal booster captures weak mobile signals from outside, amplifies them, and then broadcasts the stronger signal indoors. This way, even if you have poor reception outside, you can enjoy clearer calls and faster internet speeds inside your home or office.
- Can it work with all mobile networks? - Yes! The Tri-Band Mobile Signal Booster can work with various networks including Three, TDC, Telenor, Telia, Cbb Mobil, and many more. It boosts signals for both 2G, 3G, and 4G users simultaneously.
- How much area does the booster cover? - The booster can cover an area of up to 500 square meters, which is suitable for medium-sized houses, offices, or warehouses. This means more people can use their phones without losing signal.
- What if I have a 4G phone but no 4G service? - If you have a 4G-ready phone but you are in an area without 4G service, the booster will still allow you to use 3G services. This ensures you can make calls and use mobile data even when 4G isn't available.
- What comes in the installation kit? - The installation kit includes everything you need to get started: an outdoor antenna, indoor antenna, power adapter, outdoor cables, and the booster unit itself. All components are included in one price, making installation simple.
- Is it easy to install? - Yes, the Tri-Band Mobile Signal Booster is designed for easy installation. You'll find that you can set it up without needing expert help. Just follow the instructions in the manual!
- Can the booster improve call quality? - Absolutely! The booster enhances call quality by reducing dropped calls and providing clearer sound. If your area supports 4G Calling, your calls will be even clearer with better signal strength.
- What happens if there’s no signal outside? - It's important to note that the signal booster can only amplify existing signals. If there’s no signal outside, the booster will not work. Be sure to check your outdoor signal before purchasing.
- Do I need to upgrade any parts for better performance? - If you find that you have weak signals indoors, you might need to upgrade your external antenna or cables for better performance. Higher gain options are available to ensure you get the best signal possible.
