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.

- Q: What is a mobile phone signal booster?
A: A mobile phone signal booster is a device that helps improve the strength of your mobile phone signal. It takes the weak signal from outside your home or office, amplifies it, and sends it inside, helping you make clearer calls and use the internet more easily. - Q: How does the Three 3 mobile phone signal booster work?
A: The Three 3 mobile phone signal booster works by using an outside antenna to capture weak signals from the mobile network. It then boosts these signals, so your phone can connect more easily, improving call quality and internet speed. - Q: Is the signal booster easy to install?
A: Yes! The installation of the signal booster is designed to be simple. You just need to connect the antennas, and most people can do it themselves without any special tools. - Q: Can I use this booster with any mobile carrier?
A: The Three 3 signal booster is compatible with multiple carriers, but it's specifically designed to enhance signals from the Three network. Make sure it supports your carrier's band frequency for the best results. - Q: What is the coverage area of this booster?
A: This booster can cover an area of up to 250 square meters, which is ideal for medium-sized homes, cafes, and small offices. If you need to cover a larger space, you may need additional antennas. - Q: What do I need to check before installing the booster?
A: Before installing, check the strength of the signal outside your building. You typically need at least one to two bars of signal outside for the booster to work effectively. - Q: Will using a signal booster save my phone's battery?
A: Yes, a signal booster can help save your phone's battery. When your phone is trying hard to connect to a weak signal, it uses more power. A stronger signal means your phone can operate more efficiently and conserve battery life. - Q: How can I improve the booster performance?
A: To improve performance, ensure the outdoor antenna is in a location where it can receive the best possible signal, such as higher ground or near a window. You can also consider upgrading to a higher gain antenna. - Q: Is the signal booster safe to use?
A: Yes, the signal booster is safe. It complies with all relevant safety standards and does not emit harmful radiation. It simply amplifies the existing signal for better communication. - Q: What should I do if I still have signal issues after using the booster?
A: If you still experience issues after installing the signal booster, check to make sure everything is installed correctly. Also, make sure that there is a good signal outside. If problems persist, consider contacting customer support for further assistance.

I am really happy that I decided to order a booster on UKMobileBooster.com. Due to the pandemic of coronavirus, we have taken a decision to stay at home. But of course, in our case self-isolation could have presupposed full isolation from the whole world as the quality of our mobile signal at home used to leave much to desire.
In home O2 signal booster is a perfect solution for small cottages.
Mark Smith (UK, Wigston)
I would recommend this booster to anyone, because it’s a really good option for small cottages, the price is very adequate, and the whole system itself is safe and compact. It doesn’t waste a lot of energy while it’s working, and turns off automatically when not used, and I noticed that it actually saves the battery of my phone.

I am writing to express my deep gratitude to seller team. These guys have really helped me!

How I managed to solve my Vodafone mobile phone signal problems
Peter Barrett (UK, Somerset)
If you are fed up with mobile signal issues, try to use GBC100. We like it! I would definitely recommend this device (or other products of this seller) to anyone facing the same EE 4G signal problems in the UK. The device is really worth the price!
