It works by catching weak signals from outside and making them stronger inside your home or other places like cafes or restaurants. This means you can enjoy clearer calls and faster internet without interruptions! 2. How does the booster work? - The booster catches the mobile signal that is weak outside and boosts it to make it stronger inside. Think of it like having a loudspeaker that amplifies a quiet voice. However, if there's no signal outside at all, the booster cannot create signal, which means it won't work. 3. Can this booster help with 2G, 3G, and 4G signals? - Yes! This booster can improve signals for all these networks. So, whether you're using 2G for calls or 4G for internet, this device will help make those connections stronger and more reliable. 4.

This includes an external antenna, cables, the booster unit itself, an internal antenna, and power adapter. You won't need to buy anything extra to set it up. 6. What if my area requires longer cables? - If the standard 10-meter external cable is not enough for your area, you can upgrade to longer cables! This gives you flexibility depending on how far you need to install the external antenna from the booster. 7. How can I check if my phone will work with the booster? - You can check your phone's frequency band by dialing \*3001#12345#\* and looking for the 'Freq Band Indicator' in the information that appears. This will help you make sure your phone is compatible with the booster. 8. What happens if there is a lightning storm? - To keep your booster safe during storms, you can add a Lightning Surge Protector. This device helps protect your equipment from sudden power surges caused by lightning strikes, keeping everything working safely. 9. Can I use this booster with multiple users? - Yes! The booster can support up to 30 users at the same time, so your family, friends, or customers can all enjoy better signal strength together. 10.
