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 mobile signal booster and how does it work? - A mobile signal booster is a device that strengthens the mobile signal in your home or office. It takes the weak signal from outside, amplifies it, and sends a stronger signal inside. This way, you can enjoy better call quality, faster internet, and more reliable connections!
- Can this signal booster work for all mobile networks? - Yes! This signal booster supports multiple mobile networks including Telia, Elisa, DNA, and Tele Finland. It boosts both 3G and 4G LTE signals, ensuring that you stay connected no matter which mobile provider you use.

- Is it necessary to upgrade the external cables? - If the standard 10-meter external cable is too short for your needs, you have the option to upgrade to longer cables. This ensures that you can install your booster effectively in any location.
- What upgrades can I choose for better performance? - You can enhance your booster’s performance by upgrading to a higher gain outdoor antenna, especially if your phone shows just one or two signal bars. Additionally, you can add a lightning surge protector to keep your system safe from electrical surges.
- How can I check which frequency band my phone uses? - To find out your phone's frequency band, dial *3001#12345#* and check the 'Freq Band Indicator' in 'Serving Cell Info'. Alternatively, you can use apps like 'CellMapper' or 'Network Signal Info Pro'.
- What kind of phones are compatible with this booster? - The booster is compatible with all 3G and 4G LTE phones. If your phone supports 4G Calling (VoLTE), you’ll enjoy clearer voice calls when connected to the boosted signal!
- Will I experience dropped calls or slow internet? - With the mobile signal booster, you can eliminate dropped calls and improve your internet speed significantly. You can expect faster uploads and downloads, allowing you to stay connected and enjoy reliable service!
