What is a 3G Signal Booster? - A 3G signal booster is a device that helps improve mobile phone signals indoors. It takes in a weak signal from outside, amplifies it, and then sends a stronger signal into your home or office. This helps you make clearer calls and use data services more reliably. 2. How does the 3G Booster work? - The 3G booster works by receiving the existing mobile signals from nearby cell towers. It amplifies these signals and redistributes them inside the building, allowing you to enjoy better call quality and faster internet speeds. 3. Do I need a good signal outside to use a booster? - Yes, you need to have at least a weak signal outside for the booster to work. If there is no signal outside, the booster won't be able to amplify anything and will not improve your indoor reception. 4. How large of an area does the booster cover? - The 3G booster can cover an area of up to 2,000 square meters, which makes it suitable for large homes, offices, hotels, and other spaces where you need to improve signal strength. 5. How can I check if my phone uses the right frequency? - To check if your phone uses the correct frequency for the booster, you can dial \*3001#12345#\*, then press Call. Once you do this, click on 'Serving Cell Info' and look for the 'Freq Band Indicator'. 6. What do I need for installation? - The booster kit comes with everything you need to install it, including an outdoor antenna, indoor antenna, cables, a booster unit, and a power adapter.
