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 enhance the strength of your mobile phone signal. It works by capturing weak signals from outside, amplifying them, and then broadcasting the stronger signal inside your home or business. This can lead to better call quality and faster internet speeds, especially in areas with poor reception. It’s a great solution for those who struggle with dropped calls or slow data. - Q: Who can use the 3G & 4G LTE Mobile Signal Booster?
A: The 3G & 4G LTE Mobile Signal Booster is designed for anyone who uses mobile phones on Orange, Bouygues, or SFR networks in France. It can benefit homes, restaurants, cafes, and offices that experience weak mobile signals. It helps ensure that users can make calls and use the internet smoothly, which is great for families, businesses, and public places. - Q: How does this booster improve my mobile signal?
A: The booster improves your mobile signal in a few simple steps. First, it uses an external antenna to capture the weak signal from the nearest cell tower. Then, the booster amplifies this signal inside your building. Finally, it broadcasts the stronger signal through an indoor antenna, giving you a better connection for calls and internet use. - Q: Can multiple people use the signal booster at the same time?
A: Yes! The 3G & 4G LTE Mobile Signal Booster can support up to 25 users simultaneously. This means that several people can enjoy improved mobile reception without any drop in quality. It’s perfect for families or small businesses where multiple people need to make calls or access the internet. - Q: Is the mobile signal booster easy to install?
A: Yes, the mobile signal booster is designed for easy installation. Most users can set it up by themselves without any special tools or technical skills. The package includes all necessary components, and simple instructions are provided to guide you through the setup process. - Q: Will the booster work if I have no signal outside?
A: Unfortunately, mobile signal boosters need an existing weak signal to work. If there is no signal at all outside your home, the booster cannot amplify anything. To use this device effectively, ensure that you can access at least 1-2 bars of signal outside. - Q: What area can the 3G & 4G LTE Mobile Signal Booster cover?
A: This booster is designed to cover an area of up to 250 square meters. This means it can effectively boost mobile signals in medium-sized homes, offices, or public spaces like cafes and restaurants. - Q: Do I need to upgrade anything for better performance?
A: You might want to consider upgrading the external antenna if you receive a weak signal outside, as a higher gain antenna can significantly enhance performance. Additionally, longer external cables can be added if you need to position the antenna further away. - Q: What if I have a problem with the installation?
A: If you encounter any problems during installation, customer support is available to assist you. You can reach out for help through the website or by email. There are also detailed guides and FAQs available to help troubleshoot common issues. - Q: How do I know if this booster is right for my phone?
A: To determine if the booster is compatible, check the frequency bands used by your mobile provider. This booster works on Band 20 and Band 1. You can usually find this information in your phone's settings or through your provider's website.

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!
