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 reception of your mobile phone signals. It collects weak signals from outside, amplifies them, and broadcasts the stronger signals inside your home or office. This means you can make clearer calls and enjoy faster internet without interruptions. - Q: How does the 4G LTE & Calls signal booster work?
A: It works in three simple steps! First, the outdoor antenna receives weak signals from the mobile tower. Then, the signal booster boosts, or strengthens, these signals. Finally, the indoor antenna sends out the stronger signals throughout your home or office, making your mobile service much better. - Q: Will this booster work for all phone networks in France?
A: Yes, this booster is designed to work with many networks in France including Orange, Bouygues, and SFR. It enhances signals for both 4G LTE and voice calls for those networks, ensuring you have better connectivity no matter which one you use. - Q: Do I need a good signal outside for the booster to work?
A: Yes, the booster needs at least a small signal from outside, around 1-2 bars, to work effectively. If there is no signal outside, the booster won't be able to amplify anything, so make sure to check your outside signal strength. - Q: Can I connect multiple devices at the same time?
A: Absolutely! This signal booster can support up to 50 devices at the same time. So whether you have multiple phones, tablets, or other devices, everyone can enjoy a better signal without issues. - Q: How big of an area can this booster cover?
A: This booster can cover an area of up to 500 square meters! That’s perfect for medium-sized houses, offices, or large rooms where you need better signal coverage. - Q: Is it easy to install the signal booster?
A: Yes! The installation is quite simple. You will need to set up both the outdoor and indoor antennas and connect them to the booster. Just make sure to follow the instructions carefully, and you'll have it up and running in no time. - Q: What happens if I connect my booster when the setup isn’t complete?
A: It's very important not to power on the booster until you have completed the setup. If you do, it might not work properly. So make sure all connections are secure before turning it on. - Q: Can I expand the coverage if I need more?
A: Yes, you can! If you need more coverage, you can add extra indoor antennas. This way, you can spread the boosted signal to even larger areas. - Q: What should I do if I have problems after setting it up?
A: If you experience issues after setup, first check all your connections and positioning of the antennas. Make sure they are pointing in the right direction for the best outside signal. If problems persist, consult the user manual or contact customer support for assistance.

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.

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!
