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 the 3G - 250m2 Cell Phone Signal Booster? - The 3G - 250m2 Cell Phone Signal Booster is a device that helps improve mobile phone reception in areas where the 3G signal is weak. It works specifically on the 2100MHz frequency, which is used by Brazil's mobile networks, including Oi and Algar. This booster can cover indoor areas of up to 250 square meters, making it ideal for homes, cafes, and restaurants.
- How does a signal booster work? - A signal booster works by capturing the weak outside mobile signal with an external antenna. It then boosts that signal and distributes it through an internal antenna inside your building. This helps your phone get a better signal, making calls and using the internet much easier.
- Can I install the booster myself? - Yes! The booster kit comes with all the cables and antennas you need to set it up. Most people can install it by following a quick guide. Just make sure to place the outdoor antenna where the signal is strongest, like on your roof.
- What if there’s no signal outside? - If your outside location has no signal at all, the booster won't work because it can only amplify what it receives. It cannot create a signal on its own. You need to have at least a weak signal outside for it to function.
- How can I check if my phone is on the right frequency band? - To find out if your phone is using the right frequency band, you can dial *3001#12345#* and press call. Then look for ‘Freq Band Indicator’ on your phone’s display. If it shows Band 1, it matches the booster’s frequency.
- Can I use the booster for multiple users? - Yes! The 3G - 250m2 Booster can support up to 25 users at the same time. This is great for family use, small businesses, or anywhere more than one person needs a better signal.
- What’s included in the booster kit? - The booster kit comes with everything you need: an outdoor antenna, an indoor antenna, a booster unit, a power adapter, and cables. This all-in-one package makes it easy to get set up and enjoy improved signal reception.
- Do I need to upgrade the cables or antennas? - If the standard cables or antennas are not sufficient for your location, you have the option to upgrade to longer cables or a higher gain antenna for better signal performance. This can help if you're experiencing low reception.
- What if I receive lightning at my location? - If you are concerned about lightning strikes, you can opt for a surge protector. This device will help protect your booster and antennas from any high voltage surge caused by lightning.
- Is the booster easy to install? - Yes! The installation is quite simple. You just need to run the outdoor antenna to a spot with good reception, connect the cables to the booster inside, and plug it in. Following the setup steps in the manual can help you through the process.
