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 mobile signal booster? - A mobile signal booster is a device that helps improve the strength of your mobile phone signal inside your home or business. It makes calls clearer, speeds up texting, and allows faster internet browsing by making the weak signals from outside stronger.
- How does the 4G LTE & Calls booster work? - This booster works by capturing weak signals from your mobile network outside your home and amplifying them. Then, it sends this stronger signal inside so that you can enjoy better phone calls and faster internet without interruptions.
- Which mobile networks does the booster support? - The booster is compatible with SingTel Mobile, StarHub, M1, and Circles.Life. It works for both 2G and 4G calls, which means you can use it with all these mobile service providers at the same time.
- Will I be able to make calls if I don’t have 4G in my area? - Yes! If your phone is 4G-ready but you are in an area without 4G coverage, you can still make voice calls and send texts using the 2G network. The booster will help improve the signal for both types of calls.
- Can I install the mobile booster myself? - Yes! The booster kit comes with everything you need and is easy to install. It includes the external aerial, internal aerial, cables, and the booster unit itself. You can follow the instructions provided to set it up.
- What if the standard cable length is not enough? - If the standard 10-meter cable is too short for your setup, there is an upgrade option available to get longer external cables. This way, you can ensure the best positioning for the booster.
- What is the benefit of upgrading to a higher gain antenna? - Upgrading to a higher gain antenna can significantly improve your signal strength if your phone shows low signal bars. It helps capture more of the available signal from outside for better performance indoors.
- What is a lightning surge protector, and do I need one? - A lightning surge protector is a device that protects your mobile signal booster from damage caused by lightning strikes. It is recommended to use one, especially if you live in areas prone to storms, to keep your equipment safe.
- How much area can the booster cover? - The mobile booster can improve the signal strength in areas up to 250 square meters. This makes it a great option for homes, cafes, pubs, and other medium-sized spaces where many people may need better signal access.
- What should I do if I don't have any signal outside? - Unfortunately, if there is no signal outside, the booster will not be able to work effectively because it needs a signal to amplify. You may want to check if there are areas nearby with better reception or consider contacting your mobile service provider.
