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 signal booster?
A: A mobile signal booster is a device that helps improve the strength of your mobile phone signal. It works by receiving weak signals from outside, amplifying them, and then broadcasting the stronger signal inside your home or office. This means you can make clearer calls and enjoy faster internet. - Q: How does the 4G LTE & Calls booster work?
A: The 4G LTE & Calls booster captures weak signals from nearby cell towers using an outdoor antenna. It then boosts these signals and sends them inside your building through an indoor antenna. This process helps eliminate dropped calls and improves your internet speed. - Q: Which networks does this booster support?
A: This booster works with several mobile networks in the UK, including O2, Vodafone, giffgaff, Sky Mobile, and many others. It can enhance both 4G LTE and 2G signals, making it suitable for various users. - Q: How much area does the booster cover?

Nick Baker (UK, Leeds)
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.

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!
