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 cellphone reception in areas where the signal is weak. It works by capturing the weak signal from nearby cell towers, amplifying it, and then transmitting the stronger signal inside your home or business. This means clearer calls, faster internet, and fewer dropped calls. - Q: How does this booster work?
A: The booster has three main parts: an outdoor antenna, a booster box, and an indoor antenna. The outdoor antenna collects the weak signal from the cell tower and sends it to the booster box, which amplifies the signal. The indoor antenna then spreads this stronger signal throughout your space, helping your phones and devices work better. - Q: Will this booster work with my mobile network?
A: Yes! This booster is compatible with many mobile networks in Germany including E-Plus, Aldi Talk, Blau, and Ortel, among others. It can boost signals for both voice calls and 4G LTE data, so you can stay connected no matter which provider you use. - Q: How much area can this booster cover?
A: This booster can cover up to 250 square meters. That means it’s perfect for medium-sized homes, cafes, restaurants, and small businesses. If you need more coverage, you can add additional indoor antennas. - Q: Can I install the booster myself?
A: Yes! The installation process is quite simple. You only need to connect the outdoor antenna to the booster, install it up high where it can pick up the best signal, then connect the indoor antenna. The kit includes everything you need, making it easy even for beginners! - Q: What frequency bands does this booster support?
A: This booster supports Dual Band frequencies, specifically Band 3 and Band 8, which include 900MHz and 1800MHz. These frequencies are commonly used by mobile networks for 2G, 3G, and 4G services in Germany. - Q: Do I need a strong outside signal for the booster to work?
A: Yes, the booster requires at least a weak signal from outside in order to work effectively. If there is no signal at all, the booster will not be able to amplify anything. Ideally, you should have at least 1-2 bars of signal strength outside. - Q: How many devices can connect to the booster?
A: This mobile signal booster can support up to 25 devices at the same time. This means everyone in your household or office can enjoy better connections for calls, texts, and internet usage without interruptions. - Q: Is there a warranty for the signal booster?
A: Yes! Most signal boosters, including this one, come with a warranty. Be sure to check the details for the specific duration and what it covers. A warranty helps ensure you have support if any issues arise. - Q: How can I tell if this booster is right for me?
A: If you often experience dropped calls, slow internet, or if your service is unreliable at home or in your business, this booster can help. Just check that you have a weak signal outside, and it’s a great investment to improve your connectivity!

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.

I am writing to express my deep gratitude to seller team. These guys have really helped me!

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!
