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 Phone Signal Booster?
A: The Calls - 250m2 Mobile Phone Signal Booster is a device designed to improve mobile phone signal reception indoors. It works with major mobile networks in France, such as Orange, Bouygues, SFR, and Free, enhancing voice calls and text messages. This booster is ideal for medium-sized areas, boosting signal coverage up to 250 square meters, which is perfect for homes, offices, and public places like cafes and restaurants. - Q: How does the mobile signal booster work?
A: The mobile signal booster works in three main steps: First, it receives weak signals from a nearby cell tower through an external antenna. Next, the booster amplifies these signals and then broadcasts the stronger signal inside your home or office through an indoor antenna. This process helps ensure a better connection for phone calls and data. - Q: Do I need an existing mobile signal for the booster to work?
A: Yes, the mobile signal booster requires some existing signal from the outside. If there is no signal outside, the booster won't work since it amplifies the signals, it doesn't create them. Make sure there is at least 1-2 bars of signal outside before using the booster. - Q: How can I install the mobile signal booster?
A: To install the mobile signal booster, first connect the indoor antenna to the MS port and the outdoor antenna to the BS port. Place the outdoor antenna at a location where it can pick up the best signal, ideally with a distance of at least 10 meters from the indoor antenna. Once you have set it up, turn on the booster and adjust the outdoor antenna until the best signal is achieved. - Q: What happens if I don’t have good signal outside?
A: If you do not have a good signal outside (less than 1-2 bars), the booster will not be effective. The booster needs an existing signal to amplify; without it, the booster cannot create a functioning signal. You may want to consider other network solutions if outdoor signals are consistently weak. - Q: Can I use this booster with different mobile devices?
A: Yes, the Calls - 250m2 Mobile Phone Signal Booster is compatible with various mobile devices that work on the 2G frequency band (900MHz). This includes most smartphones, tablets, and devices used with Orange, Bouygues, SFR, and Free networks in France. - Q: What if I want to cover a larger area?
A: If you need to cover a larger area, you can expand the coverage by adding additional indoor antennas. This is useful when the outside signal is strong enough, and you want to ensure that multiple rooms or larger areas receive improved signal strength. - Q: Is it necessary to upgrade the external cables?
A: If the standard 10 meter external cable that comes with the booster is not long enough for your needs, you have the option to upgrade to longer cables. This can help ensure that the outdoor antenna is placed in the best position for signal reception. - Q: What is the purpose of the Lightning Surge Protector?
A: The Lightning Surge Protector is designed to protect your mobile signal booster equipment from damage caused by lightning strikes. It can handle high amperage surges, ensuring that your device remains safe and operational even during storms. - Q: Are there any specific installation tips I should know?
A: Yes, before installing your booster, make sure to not power it on until the installation is complete. Additionally, always check the signal strength after setup and adjust the outdoor antenna for the best reception. Following these steps will help you get optimal performance from your mobile signal booster.

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!
