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 signals for your phone. It captures weak signals from outside, amplifies them, and makes them stronger so you can make calls and use the internet better in your home or office. This means no more dropped calls or slow internet! - Q: How do I install the mobile signal booster?
A: Installing a mobile signal booster is pretty simple. First, connect the outdoor antenna to the booster and place it in a spot where it can get good signals from the cell tower. Then, connect the indoor antenna inside your home. Finally, plug in the booster and enjoy better signal! Be sure to read the instructions that come with it. - Q: What kind of coverage can I expect?
A: This booster can cover an area up to 1,000 square meters. This means it’s perfect for large homes, offices, hotels, or warehouses. If your phone has poor signal strength, this device can help you connect better throughout the space! - Q: Can multiple users use the booster at once?
A: Yes, the mobile signal booster can support up to 100 users at the same time! So, everyone in your household or office can enjoy a better connection without interfering with each other’s service. - Q: Which mobile networks are supported?
A: The booster works with various networks in Saudi Arabia including STC, Mobily, Zain, Lebara, Friendi, and Virgin Mobile. This makes it a great choice no matter which provider you and your family use! - Q: Do I need a good signal outside for the booster to work?
A: Yes, a mobile signal booster can only amplify existing signals, not create new ones. If your outside signal is very weak or absent, the booster won’t function properly. A signal with at least 1-2 bars is recommended for the booster to work effectively. - Q: What do I do if I still have signal problems?
A: If you're experiencing ongoing signal issues, make sure the outdoor antenna is placed correctly and isn't blocked. Additionally, check whether you have enough signal coming in from outside. If things don’t improve, consider reaching out to customer support for more help. - Q: Is this device easy to maintain?
A: Yes, the mobile signal booster is designed for easy installation and maintenance. Once it is set up, you won’t need to do much. Just check occasionally to ensure the antennas are clear of any obstructions, and it should work well. - Q: What is the warranty on the mobile signal booster?
A: Most mobile signal boosters come with a manufacturer’s warranty, typically lasting around 1-2 years. Make sure to keep the receipt and check the warranty policy for specific details. - Q: Can I expand the coverage with more antennas?
A: Yes, if you find that certain areas of your space still have weak signal, you can add more indoor antennas for wider coverage. This is especially useful in larger or multi-story buildings.

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!
