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 the Calls - 250m2 Mobile Signal Booster?
A: The Calls - 250m2 Mobile Signal Booster is a device designed to strengthen mobile phone signals in medium-sized areas, up to 250 square meters in Germany. It enhances voice call and text message reception for major networks like E-Plus, O2, Telekom, Vodafone and more. This is particularly useful for homes, cafes, and restaurants where signal is often weak. - Q: How does the signal booster work?
A: The signal booster works in three simple steps. First, the outdoor antenna captures the existing mobile signal from the cell tower. Next, the booster amplifies this signal, making it stronger. Finally, the indoor antenna broadcasts the boosted signal throughout the room, ensuring your devices have excellent reception. - Q: Can I use the booster if I have a weak signal outside?
A: No, the booster cannot create a signal from nothing. It requires at least 1 or 2 bars of signal outside to function effectively. If there's no signal beyond your walls, the booster will not work. - Q: Is the installation difficult?
A: Not at all! The installation is straightforward. You just connect the indoor and outdoor antennas, position them correctly, and turn on the device. Detailed instructions are provided in the user manual to guide you through each step. - Q: What areas can the booster cover?
A: The booster is designed to cover a space of up to 250 square meters. This coverage is perfect for homes, cafes, restaurants, offices, and more. If you need to cover a larger area, you can add more indoor antennas. - Q: What do I do if I have no signal at all?
A: If you have no signal outside, the booster will not work. You need to ensure that there is at least a faint signal outside (1-2 bars) before the booster can amplify it inside your space. - Q: What happens during a storm?
A: If your outdoor antenna is hit by lightning, there is a risk of damage to your booster. To prevent this, you can purchase a lightning surge protector that is easy to install and will protect your equipment from surges caused by storms. - Q: What upgrades are available for the booster?
A: You can upgrade to a longer external cable, a higher gain Yagi antenna for better performance, and a lightning surge protector to safeguard your device. These upgrades can help improve signal reception and overall effectiveness. - Q: Can multiple devices use the booster at the same time?
A: Yes! The Calls - 250m2 Mobile Signal Booster can support up to 25 devices simultaneously. This means you, your family, or colleagues can all enjoy improved mobile signal at the same time. - Q: What is Band 8 and why does it matter?
A: Band 8 refers to a specific frequency used by mobile networks for 2G services. This booster specifically enhances signals on Band 8, which is necessary for making voice calls and sending texts on compatible devices in Germany.

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!
