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? - A mobile signal booster is a device that helps improve the mobile reception in your area. It takes weak signals from outside, amplifies them, and sends stronger signals inside your home or office. This helps you make clear calls and use data without interruptions.
- How does the 3G - 300m2 Booster work? - This booster works by amplifying the 3G signal on the 2100MHz frequency used by networks like Cosmote, Vodafone, and Wind in Greece. It can boost signals indoors for areas up to 300 square meters, making internet browsing and calls more reliable.
- Can it work if there's no signal outside? - No, the booster needs a weak signal outside to amplify it. If there's no signal outside, the booster won't be able to help. It's important to check that you have some level of signal where you plan to install it.
- Is it easy to install? - Yes, it's designed for easy installation! The kit includes everything you need. Simply place the outdoor antenna where you get the best signal, connect it to the indoor booster, and you're ready to go!
- Can multiple users use it at the same time? - Yes, the 3G Mobile Signal Booster can support up to 30 users simultaneously. This means that multiple devices can enjoy better reception at the same time.
- What’s included in the booster kit? - The kit comes with a booster unit, an outdoor antenna, an indoor antenna, a power adapter, and a 10-meter outdoor cable. This means you have everything you need to get started!
- What should I do if I have weak indoor signals? - If your indoor signal is weak, try placing the outdoor antenna in a different spot where the signal is stronger. The higher you can place it, like on a rooftop, the better the reception can be.
- What is an upgrade option for the antennas? - You can upgrade to a higher gain antenna if you have a weak signal or only a couple of bars on your phone. This helps improve the performance of the booster by capturing better signals.
- How can I check my signal strength? - You can check your signal strength by dialing *3001#12345# on your phone and checking the 'Freq Band Indicator' for the frequency band information. You can also use apps like 'CellMapper' for more details.
- Is there a warranty or return policy? - Yes, we offer a warranty on our products as well as a return policy. If you encounter any issues or the product doesn’t meet your needs, you can reach out to us for assistance.
