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.

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 cell phone signal booster? - A cell phone signal booster is a device that helps improve the reception of your mobile phone by amplifying weak signals. It works by capturing the existing weak signal from outside, boosting its strength, and then redistributing it inside your home or office. This way, you can enjoy clearer calls and faster text messages.
- How does the Calls - 250m2 signal booster work? - The Calls - 250m2 signal booster operates on the 900MHz frequency. It is designed specifically for Brazilian mobile networks like TIM, Claro, Oi, and Algar to enhance voice calls and SMS messages for spaces up to 250 square meters. It won’t create a signal but will improve the existing one, helping you stay connected.
- Will this booster work if there's no signal outside? - No, the signal booster can only amplify signals it receives from outside. If you have no signal outside, the booster won't be able to help you. Ideally, you should have at least a weak signal outside for the booster to work effectively indoors.
- How many devices can connect to the booster? - The Calls - 250m2 booster can support up to 25 devices at the same time. This means all your family members or friends can enjoy enhanced signal strength without interfering with each other’s connectivity.

The kit includes everything needed for installation: outdoor and indoor antennas, cables, and the booster unit itself. Just follow the provided instructions, and you can get it set up in no time!
- What should I consider when choosing an external aerial upgrade? - If your phone shows only 1 or 2 signal bars indoors, it’s a good idea to upgrade to a higher gain Yagi antenna for better performance. A stronger aerial can significantly improve signal quality, especially if you're in an area with weak reception.
- What is the purpose of a surge protector? - A surge protector helps protect your signal booster and other equipment from potential damage caused by lightning strikes or electrical surges. It's a safety device that ensures your equipment remains functional even during storms.
- Can I expand the cable length for the installation? - Yes, if the standard 10-meter cable included in the booster kit isn’t long enough for your setup, you can upgrade to longer cables like 20, 30, 40, or even 50 meters, ensuring you can place your antennas in the best locations.
- How long is the warranty on the signal booster? - The warranty period for the Calls - 250m2 signal booster is typically one year. This means that if you face any issues during that time, you can get support or a replacement if the device is found to be faulty.
