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 does the Calls - 150m2 Cell Phone Signal Booster do? - The Calls - 150m2 Cell Phone Signal Booster improves phone signals for voice calls and text messages on specific networks in Brazil like TIM, Claro, Oi, and Algar. If you often find yourself struggling to make a call or send a text, this device can enhance your signal strength and improve coverage within an area of up to 150 square meters, making it perfect for small homes or offices.
- How do I install the cell phone signal booster? - Installing the cell phone signal booster is easy! First, place the outdoor antenna where it can catch the best signal, like on your roof. Then, run the included cable into your home to the booster unit. Next, connect the indoor antenna to the booster. Finally, plug in the power supply, and your booster is ready to help strengthen your phone signal!
- Can the booster work if there is no signal outside? - Unfortunately, the booster can only make weak signals stronger. If there is no signal at all outside, the booster won't work. It's important to find a location outside where you do have some signal so the booster can amplify it indoors. If you're unsure about your signal outside, you can check using a mobile app.
- Is the booster suitable for multiple users? - Yes! The Calls - 150m2 Cell Phone Signal Booster can support up to 15 users simultaneously. This means you and your family or coworkers can enjoy improved signal strength for calls and texts at the same time.
- What is the gain of the booster and what does it mean? - The booster has a gain of at least 45 dB for the upward signal it sends and 50 dB for the signal it receives. A higher gain means that the device can amplify weaker signals better, leading to clearer calls and faster text message delivery.
- What if I need longer cables for installation? - If the standard 10-meter cables are not long enough for your installation, you can upgrade to longer cables. Options are available for 20, 30, 40, or even 50 meters to ensure you can connect the booster effectively no matter the distance.
- Can I add additional antennas to improve performance? - Yes, you can upgrade to a higher gain antenna which can enhance performance significantly, especially if you find your phone showing a weak signal with just 1 or 2 bars. This upgrade can help in boosting the signals better inside your home.
- What kind of power does the booster need? - The cell phone signal booster comes with a power adapter that accepts between 100 to 240 volts. This means it can work with standard outlets in most homes, so you don't need any special installations to power it up.
- How do I check if my mobile signal needs boosting? - To check your mobile signal strength, you can dial *3001#12345# on your iPhone and look for the 'Freq Band Indicator' under 'Serving Cell Info'. Alternatively, you can use apps like CellMapper or Network Signal Info Pro to assess your current signal strength.
