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 strengthens weak cellular signals so that your phone can connect better. It helps you make calls, send messages, and use the internet more easily, especially in areas where the signal is low.
- How does the 3G & 4G LTE booster work? - The booster captures the mobile signal outside your home, makes it stronger, and then spreads it indoors. It works specifically on 1800MHz and 2100MHz frequencies, improving connectivity for both 3G and 4G LTE networks in Greece.
- Will this booster work for all mobile networks? - Yes, this booster supports all major mobile networks in Greece, including Cosmote, Vodafone, and Wind. It can enhance 3G and 4G LTE signals for various users at the same time.
- What size area does the booster cover? - The signal booster can cover up to 250 square meters, which makes it perfect for medium-sized spaces like homes, cafés, and clubs. It allows multiple users to enjoy better signal strength in that area.
- Do I need a special phone to use this booster? - No special phone is needed! If your phone can work with 3G or 4G networks, it will benefit from the booster. However, your phone must have access to a signal outside for the booster to be effective.
- What if there's no signal outside my home? - The booster can only strengthen existing signals. If there is no signal available outside, the booster won't be able to work. It needs to capture a weak signal to amplify it.
- Can I install the booster myself? - Yes! The booster kit comes with everything you need for easy installation, including cables and antennas. You can set it up without having to hire a technician.
- What upgrades are available for the booster? - You can upgrade to a stronger external aerial for better performance or add a lightning surge protector to keep your equipment safe from power surges. These options can improve your signal reception even more.
- How can I check which frequency band my phone uses? - To find out your phone's frequency band, dial *3001#12345#* on an iPhone and check 'Freq Band Indicator' in 'Serving Cell Info'. You can also use apps like CellMapper for the same information.
- Is the booster compatible with VoLTE (4G Calling)? - Yes! If your phone supports VoLTE and there is 4G coverage in your area, the booster will enable clearer voice calls over the 4G network.
