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.

A: This signal booster can cover a large area of up to 2000 square meters. That means it can work for big houses, offices, hotels, and even warehouses! It's designed to help many people use their phones at the same time without losing signal. - Q: What mobile networks can I use the booster with?
A: You can use this booster with several mobile networks like Three, TIM, Vodafone, and Wind. If your phone connects to one of these networks, you should see better calls and faster internet with the booster! - Q: How do I know if I need a signal booster?
A: If you often experience dropped calls, slow internet, or if your phone shows one or two bars of signal at home, then a signal booster could help you. It can't create a signal, so it’s best used in areas where you can already pick up a little signal outside. - Q: Is it easy to set up the booster?
A: Yes! Setting up the booster is quite simple. You'll connect the indoor and outdoor antennas using the provided cables. Just place the outdoor antenna where it gets a good signal, and you're ready to enjoy better reception inside! - Q: Can I use the booster for both calls and internet?
A: Absolutely! The booster is designed to enhance both phone calls and internet data. So whether you’re uploading photos, watching videos, or making calls, you will have a better connection. - Q: What happens if I don’t have any signal outside?
A: The booster can only make weak signals stronger. If there’s no signal outside, it won't work inside. It's necessary to have at least a little signal outside so that the booster can do its job. - Q: Do I need to buy any extra parts?
A: The booster comes with everything you need, including antennas and cables. However, if your area is very large or has special needs, you might consider additional antennas or longer cables which are available for purchase. - Q: Is there customer support if I have questions?
A: Yes! If you have any questions or need help with your signal booster, customer support is available to assist you. They can help with installation or any issues you might encounter. - Q: Will the booster work with my 4G phone?
A: Yes! If your phone is 4G capable, the booster will work with it to provide improved call quality and faster internet. Just make sure your phone can connect to the supported frequencies of the booster.

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!
