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.

- What is the Calls - 250m2 Mobile Signal Booster? - The Calls - 250m2 Mobile Signal Booster is a device that improves mobile phone signals for Cosmote, Vodafone, and Wind networks in Greece. It boosts signals specifically for voice calls and texts on the 900MHz frequency, covering an area of up to 250 square meters, making it perfect for homes, cafes, and restaurants.
- How does the signal booster work? - The booster captures weak signals from outside and amplifies them, sending a stronger signal indoors. This helps ensure you can make and receive phone calls and texts without interruption. However, if there is no signal outside, the booster cannot create one.
- Can I install the signal booster myself? - Yes! The signal booster comes with all the necessary tools and instructions for easy installation. Just follow the steps provided, and you can set it up yourself in no time!
- What if I need longer cables for installation? - If the standard 10-meter cable that comes with the booster isn't long enough, you can choose to upgrade to longer cables, ranging from 20 to 50 meters, so you can position your antennas for the best signal.
- What type of phone signals does this booster support? - This booster supports 2G signals for voice calls and text messages across several mobile networks, including Cosmote, Vodafone, and Wind. It enhances signals for any standard mobile device that operates on these networks.
- Can I use the booster if I have a 3G or 4G phone? - Yes, while this booster is designed for 2G signals, it can help improve the overall reception in areas where 2G signals are available. However, for 3G or 4G signals, you may want to consider a different booster model that supports those frequencies.
- Will the booster work in my area? - To check if the booster will work in your area, you should have a usable mobile signal outside. You can test your phone's signal strength using specific apps or by calling a special number on your phone. If there's no signal outside, the booster won’t be effective.
- Do I need to get any special permits to use a signal booster? - Generally, using a mobile signal booster does not require permits. However, it’s a good idea to check local regulations regarding their use to ensure compliance with any applicable laws.
- What should I do if the booster is not working properly? - If you're having trouble with your signal booster, first check that all components are connected properly and that the antenna is positioned correctly. If the problem persists, consult the troubleshooting guide provided or contact customer support for assistance.
