What does the Calls - 150m2 Cell Phone Signal Booster do? - The Calls - 150m2 Cell Phone Signal Booster improves phone signals for voice calls and text messages on specific networks in Brazil like TIM, Claro, Oi, and Algar. If you often find yourself struggling to make a call or send a text, this device can enhance your signal strength and improve coverage within an area of up to 150 square meters, making it perfect for small homes or offices. 2. How do I install the cell phone signal booster? - Installing the cell phone signal booster is easy! First, place the outdoor antenna where it can catch the best signal, like on your roof. Then, run the included cable into your home to the booster unit. Next, connect the indoor antenna to the booster. Finally, plug in the power supply, and your booster is ready to help strengthen your phone signal! 3. Can the booster work if there is no signal outside? - Unfortunately, the booster can only make weak signals stronger. If there is no signal at all outside, the booster won't work. It's important to find a location outside where you do have some signal so the booster can amplify it indoors. If you're unsure about your signal outside, you can check using a mobile app. 4.

What is the gain of the booster and what does it mean? - The booster has a gain of at least 45 dB for the upward signal it sends and 50 dB for the signal it receives. A higher gain means that the device can amplify weaker signals better, leading to clearer calls and faster text message delivery. 6. What if I need longer cables for installation? - If the standard 10-meter cables are not long enough for your installation, you can upgrade to longer cables. Options are available for 20, 30, 40, or even 50 meters to ensure you can connect the booster effectively no matter the distance. 7. Can I add additional antennas to improve performance? - Yes, you can upgrade to a higher gain antenna which can enhance performance significantly, especially if you find your phone showing a weak signal with just 1 or 2 bars. This upgrade can help in boosting the signals better inside your home. 8. What kind of power does the booster need? - The cell phone signal booster comes with a power adapter that accepts between 100 to 240 volts. This means it can work with standard outlets in most homes, so you don't need any special installations to power it up. 9. How do I check if my mobile signal needs boosting? - To check your mobile signal strength, you can dial \*3001#12345# on your iPhone and look for the 'Freq Band Indicator' under 'Serving Cell Info'.
