Application Scenarios




- What is a 3G signal booster? - A 3G signal booster is a device that helps to improve your mobile phone's signal, especially when you're in areas where the signal is weak. It works by capturing the existing weak signal, amplifying it, and then sending the stronger signal to your phone. This means you can make calls and use mobile data more reliably.
- Who can benefit from using a 3G signal booster? - Anyone who experiences poor mobile service in their home, car, or caravan can benefit from a 3G signal booster. This includes people traveling in remote areas, those living in buildings with thick walls, and even families with multiple mobile networks that need a better signal.
- How do I know if I need a signal booster? - If you often have dropped calls, struggle to send text messages, or find that your internet is slow, then you might need a signal booster. You might also consider one if you notice that certain parts of your home or vehicle have weak mobile reception.
- Will a signal booster work for all mobile networks? - Yes, the 3G signal booster mentioned works with several networks in the Czech Republic, including Vodafone, T-Mobile, Mobil CZ, Kaktus, and O2. Just make sure your phone operates on the supported frequencies of 900MHz or 2100MHz.

- How does the external aerial work? - The external aerial, which can be mounted outside your car, connects to the booster inside. It captures the incoming signal from the mobile network and sends it to the booster to amplify. A stable aerial usually has three magnets for a firm grip.
- Is a signal booster safe to use? - Yes, using a signal booster is safe. It helps improve your phone's reception, which can actually reduce the amount of radiation your phone emits when it's trying to connect to a weak signal.
- What should I check before purchasing a 3G signal booster? - Before buying a 3G signal booster, check your mobile provider to see which frequencies they use in your area - either 900MHz or 2100MHz. You can also download apps like 'Network Signal Pro' to help confirm this.
