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 cell phone signal booster?
A: A cell phone signal booster is a device that helps improve your phone's reception. It does this by taking a weak cell signal from outside, making it stronger, and then broadcasting that boosted signal inside your home or office. This means you can make calls, send texts, and use the internet more easily, especially in places where it was hard to get a signal before. - Q: How does the 4G LTE Signal Booster work?
A: The 4G LTE signal booster works in three steps. First, it has an outdoor antenna that catches the weak phone signal from nearby cell towers. Next, the booster makes that signal stronger. Finally, it sends this stronger signal inside your home or office so your phone can connect better. This helps you make calls and use the internet without interruptions. - Q: Who can benefit from using this booster?
A: Anyone who struggles with poor phone reception can benefit from this booster! It's especially useful for people who live or work in large buildings, offices, or areas with a weak signal. If you watch videos online or use apps that need fast internet, this device can really help you get faster and clearer connections. - Q: Is it difficult to install the booster?
A: Not at all! Installing the cell phone booster is quite simple. You only need to connect a few cables to the indoor and outdoor antennas, set them up properly, and then you’re good to go. You don’t need to be an expert; just follow the instructions, and you’ll have it ready in no time. - Q: What types of mobile networks does the booster support?
A: This booster supports several mobile networks in the United States, including U.S. Cellular and Illinois Valley Cellular. It boosts 4G LTE signals that operate on the 850MHz frequency, making it compatible with many devices using those networks. - Q: Will the booster work if I have no signal outside?
A: Unfortunately, no. The booster needs a weak signal from outside to amplify it. If there is no signal outside your building, the booster won't work. Ideally, you need at least 1-2 bars outside for the booster to help. - Q: What is the coverage area of this booster?
A: This signal booster can cover areas of up to 2,000 square meters. That means it's great for large homes, offices, warehouses, and even hotels! So if you're in a big area and need better reception, this booster can help. - Q: Can I add more antennas to improve coverage?
A: Yes! If you find that you're still not getting strong coverage throughout your space, you can add more indoor antennas. This helps spread the boosted signal to more areas, ensuring better reception in every corner of your room. - Q: What do I do if I have questions or need help?
A: If you have questions or need assistance, it's best to reach out to the customer service team from where you bought the booster. They are usually friendly and can help you with installation, setup, or any other concerns you may have. - Q: How can I check if my phone supports the 4G LTE Band?
A: To check if your phone supports the 4G LTE band, you can look it up in your phone's settings. For iPhones, dial *3001#12345#* and for Android, download the 'LTE Discovery' app. This will help you find out if your device can work with 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.

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!
