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 helps improve weak 3G signals in your area. It works by capturing the existing signal from outside and amplifying it so you can enjoy better phone calls and faster internet in your home or business.
- How does the signal booster work? - The booster collects the weak mobile signal from outside, strengthens it, and then sends it inside your home or business. It won't create a new signal; it just makes the existing one stronger, so you need to have some signal available outside for it to work.
- Where can I use the 3G booster? - You can use the 3G Mobile Signal Booster in places like homes, cafes, restaurants, clubs, and pubs. It covers an area of up to 250 square meters, providing better signal coverage wherever you need it.
- Can I install the signal booster myself? - Yes! The kit comes with everything you need for installation, including antennas and cables. You can easily follow the instructions included in the package to set it up.
- What happens if there is no signal outside? - If there is no mobile signal outside, unfortunately, the booster will not work. It needs some outside signal to amplify and redistribute it inside.
- What frequency does the booster support? - This booster specifically supports the 3G frequency of 2100MHz, which is commonly used by mobile networks in the Philippines, especially Sun Cellular.
- How many devices can connect at once? - The 3G Mobile Signal Booster can support up to 25 devices at the same time, allowing multiple users to benefit from the improved signal.
- What if I need longer cables for installation? - If the standard 10-meter cables are not long enough for your setup, you can upgrade to longer external cables to ensure proper installation and coverage.
- Is there a way to protect the booster from electrical surges? - Yes, you can upgrade your kit with a Lightning Surge Protector. This device will help protect your booster from electrical surges caused by lightning, ensuring its longevity and performance.
- How can I check if the booster is installed correctly? - Once you set up your booster, you can check your phone's signal strength using the 'Serving Cell Info' option on your phone. You can dial *3001#12345#*, press call, and view your current signal frequency to ensure everything is functioning well.
