What does a mobile signal booster do? - A mobile signal booster helps make your phone calls and internet faster by strengthening the mobile signals received from outside. This means if you have weak signals at home or in your office, the booster will improve the quality of phone calls and data connections, helping you stay connected easily. 2. How does the booster work indoors? - The mobile signal booster has an outdoor antenna that collects signals from your mobile network, which are then amplified inside your space. It works on several frequencies, so it can boost various types of signals like 2G, 3G, and 4G for different networks in Indonesia, making your calls clearer and letting you use the internet without interruptions. 3. Can multiple people use the booster at the same time? - Yes! Our mobile signal booster allows up to 50 people to use the boosted signals simultaneously. This is especially helpful in homes, offices, or places where many people might need to make phone calls or use the internet at the same time. 4. What do I need to install the booster? - When you purchase the mobile signal booster, it includes everything you need for installation: an external antenna, cables, the booster itself, an internal antenna, and a power adapter. This means you won't need to buy any extra tools or equipment to get it working! 5. How do I know if the booster will work for me? - The booster can only amplify signals that already exist outside. If there are no signals available, it won’t work. You can check the signal strength outside or contact your mobile provider to find out about coverage in your area before purchasing. 6. What kind of mobiles work with this booster? - The mobile signal booster works with a variety of mobile services, including Telkomsel, Indosat, XL Axiata, and Three 3. As long as your phone supports these networks and is capable of using 2G, 3G, or 4G data, the booster will enhance your calls and internet speed. 7. Can I customize the cables for my setup? - Yes! If the standard 10-meter cable length isn’t enough for your space, you can upgrade to longer cables. This way, you can properly position the antenna to receive the best signal without any hassle. 8. What if I have a weak signal indoors? - If your indoor signal is weak with only 1 or 2 bars on your phone, it’s a good idea to consider upgrading to a higher gain antenna. This upgrade can help improve the performance of your mobile signal booster, making your calls and internet even better. 9. How do I protect the booster from lightning? - You can add a lightning surge protector to your mobile signal booster system. It is easy to install and will help protect your equipment from power surges caused by lightning strikes, ensuring your booster remains safe during storms. 10. Is it difficult to install the mobile signal booster? - Not at all! The mobile signal booster kit is designed for easy installation.
