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 phone signal inside your home or office. It captures the weak signal from outside, boosts it, and then redistributes the stronger signal inside. This can help you make clear calls and send text messages without interruptions.
- Who can use the Calls - 150m2 Mobile Signal Booster? - The Calls - 150m2 Mobile Signal Booster works with O2, Telekom, and Orange networks in Slovakia. It's designed for anyone who experiences weak mobile signals in their home or office, especially in small spaces like apartments.
- How large of an area does this booster cover? - This booster can improve the mobile signal in an area of up to 150 square meters. It's great for small apartments or offices where the signal is weak.
- Can I use the booster if I have no signal outside? - No, the booster needs an existing signal outside to work. If there is no signal outside, the booster cannot create one, and therefore, it won't help improve your indoor signal.
- What if my area needs a longer cable? - If the standard 10-meter external cable included with the booster isn't long enough for your needs, you have the option to upgrade to a longer cable. You can choose cables of different lengths to fit your space.
- How do I install the Mobile Signal Booster? - Installation is quite easy! First, place the outdoor antenna where the signal is best. Next, connect it to the booster indoors using the cable provided. Lastly, set up the indoor antenna and plug everything in. It's useful to do a 'loose' setup first to check the best spots before finalizing your installation.
- What upgrades are available for the booster? - You can upgrade to a higher gain Yagi antenna for better performance, or add a lightning surge protector to safeguard your equipment from any electrical surges. These upgrades can enhance the functionality of your booster.
- How does the booster improve my phone calls? - The booster strengthens the mobile signal for calls, allowing you to speak clearly and preventing dropped calls. It also improves the speed of sending and receiving text messages, ensuring you stay connected without interruptions.
- What do I do if the booster doesn’t work? - If your booster is not working, first check to make sure it is installed correctly and that there is a signal outside to amplify. If problems persist, contact customer support for further assistance.
- How can I check my mobile frequency band? - To check your mobile frequency band on an iPhone, dial *3001#12345#* and press the call button. Then, tap on 'Serving Cell Info' and look for the 'Freq Band Indicator.' This will tell you if the booster will work with your phone.
