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 strengthens the mobile signal in your home or office. It takes weak signals from outside, amplifies them, and then sends the stronger signal inside. This helps you make clearer calls and send text messages without interruptions. - Q: How does the Calls - 500m2 Booster work?
A: This booster works by first receiving weak mobile signals through an outdoor antenna. It then boosts the signal and broadcasts it inside your space, improving the quality of your calls and texts. You will notice fewer dropped calls and faster message delivery. - Q: What areas can the 500m2 Booster cover?
A: The 500m2 Mobile Signal Booster can improve signal coverage for areas up to 500 square meters. This makes it suitable for medium-sized homes, offices, and even warehouses where good mobile service is needed. - Q: Which mobile networks does this booster support?
A: This booster works with several networks in Germany, including E-Plus, O2, Telekom, and Vodafone. It enhances voice calls and text messages for all operators using the 900MHz band. - Q: Do I need a strong outside signal for the booster to work?
A: Yes, the booster requires at least 1-2 bars of signal outside to function effectively. If there's no signal outside, the booster cannot create a signal; it only amplifies what it receives. - Q: Can I use this booster for 4G internet?
A: This specific booster is designed mainly for 2G voice calls and texts. If you're looking to enhance 3G or 4G internet signals, you might want to check if other models support those frequencies. - Q: How do I install the mobile signal booster?
A: Installation is straightforward! You connect the outdoor antenna to the booster, position it for the best signal, and then connect the indoor antenna to broadcast the boosted signal. Always make sure to follow the provided installation guide. - Q: Can I expand the coverage with more indoor antennas?
A: Yes! You can expand the signal coverage by adding additional indoor antennas if you have a strong external signal. This will help reach more areas in your home or office where the signal is weak. - Q: What should I do if I experience problems with the booster?
A: If you face issues, check the connections, ensure the outdoor antenna is pointing to the strongest external signal, and make sure there is good external signal strength (1-2 bars). If problems persist, consult the user manual or customer support for assistance. - Q: Is this booster safe to use?
A: Yes, the Calls - 500m2 Mobile Signal Booster is designed to be safe for everyday use. It complies with regulatory standards and automatically turns off when not needed, which also helps save energy.

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!
