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 your cell phone signal. It works by receiving weak signals from outside, amplifying them, and then sending the stronger signal inside your home or office. This allows you to make clearer calls and enjoy faster internet. - Q: How does the 3G & Calls - 500m2 booster work?
A: The 3G & Calls - 500m2 booster uses two antennas. One is placed outside to catch the weak signal from the cell tower. The other is placed inside to spread the stronger signal throughout your space. This makes it easier to make calls and use the internet. - Q: Who can use this booster?
A: This booster can be used by anyone living in Saudi Arabia who has issues with mobile signal from networks like STC, Mobily, Zain, Lebara, Friendi, and Virgin Mobile. It's suitable for homes, offices, or other places needing better signal coverage. - Q: What area can it cover?
A: This booster can cover an area up to 500 square meters. This means it's great for medium-sized homes or small businesses, helping many people stay connected at once. - Q: Do I need to have some signal for it to work?
A: Yes, you need to have at least a weak signal outside for the booster to work. If there's no signal outside, it won't make the signal stronger inside. - Q: Is it difficult to install?
A: No, the installation is quite simple. You'll just need to follow the instructions provided, which guide you through connecting the antennas and setting up the device to ensure the best signal. - Q: Can I use it for multiple devices?
A: Yes! This booster can support up to 50 devices at the same time. So, family members or coworkers can all benefit from the improved signal together. - Q: What happens if there's a lightning storm?
A: To protect your booster from lightning strikes, you can add a surge protector. This device will help safeguard the booster and keep it working even during storms. - Q: Will it help with dropping calls?
A: Yes, using this booster can reduce dropped calls significantly. With a stronger signal, you can expect clearer conversations and fewer interruptions. - Q: How can I choose the right booster for my needs?
A: To choose the best booster, first check which frequency bands your mobile network uses. The website has a guide to help you figure this out. If you're unsure, you can also contact customer service for advice!

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!
