How does the mobile signal booster work? - The booster amplifies existing mobile signals from outside your home, which improves the quality of calls and internet inside your apartment or office.

It’s a dual band booster, meaning it enhances signals on both 800MHz and 1800MHz frequencies at the same time, making it suitable for households with different mobile providers. 5. What if my phone doesn't support 4G? - If your phone does not support 4G, you can still use it for voice calls and texts. The booster improves the overall signal quality, so even if you're not in a 4G area, you’ll still have improved service for calls and messages. 6. Can everyone in the house use this booster? - Yes! The booster can support up to 10 users at the same time. This means that all family members or colleagues can benefit from better signals when using their phones. 7. What do I need to use this booster? - You will need a mobile signal outside your building for the booster to work effectively. The kit comes with everything for easy installation, including the booster unit, outdoor antenna, indoor antenna, cables, and a power adapter. 8. How do I check my mobile network frequency? - You can check your mobile network frequency by dialing \*3001#12345#\* on an iPhone, which will give you access to the 'Serving Cell Info' where you can find the frequency band indicator. Alternatively, you can use apps like CellMapper or Network Signal Info Pro. 9.
