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 3G Mobile Signal Booster? - A 3G Mobile Signal Booster is a device that helps to improve the mobile phone signal in an area. It catches the weak signal from outside, amplifies it, and then broadcasts the stronger signal inside your home or business. This makes it easier to make calls and use the internet on your phone.
- How does the 3G booster work? - The 3G booster works by capturing the weak mobile signal from outside your building. It then strengthens this signal and sends it to your devices inside, allowing you to enjoy better call quality and faster internet. Just remember, it can only amplify existing signals; if there's no signal outside, it won't work.
- What areas can this booster cover? - This booster can cover an indoor area of up to 300 square meters. That makes it great for homes, cafes, restaurants, clubs, and more! It helps everyone inside stay connected without dropped calls or slow internet.
- Is the installation easy? - Yes! The kit comes with everything you need to set it up, including detailed instructions. You’ll get an outdoor antenna, indoor antenna, cables, and a power adapter. Even if you’re not very tech-savvy, you can install it by following the easy steps provided.
- Can I use this booster with any mobile phone? - Yes, the booster is designed to work with any mobile phone that uses the 3G network on the 2100MHz frequency, which many carriers use. So, as long as your phone supports this frequency, you can use the booster.
- Do I need to check my mobile frequency? - Yes, it’s a good idea to check your mobile frequency before buying the booster. You can do this by dialing *3001#12345# and looking for the 'Freq Band Indicator' on your iPhone. This will tell you if you are on the right frequency for the booster.
- What if I don’t have a signal outside? - If there is no signal where you are, the booster won't be able to help. It’s important that there is at least some signal outside, as the booster amplifies that existing signal instead of creating a new one.
- Can I upgrade my external cables if needed? - Absolutely! If you find that the standard 10-meter cables are not enough to reach from the outdoor antenna to the booster, you can upgrade to longer cables. This will help ensure you have a good connection for your booster.
- What is a surge protector, and do I need one? - A surge protector is a device that helps to protect your booster from electrical surges, like those from lightning strikes. It's a good idea to have one installed to keep your equipment safe, especially in areas prone to storms.
- How many users can connect to the booster at once? - This particular booster can support up to 30 users at the same time. That means multiple people can enjoy better signals and faster internet without any issues!
