What is a cell phone signal booster? - A cell phone signal booster is a device that helps improve weak cellular signals inside buildings. It takes the existing signal from outside, amplifies it, and redistributes it throughout your home or office. This can help make your phone calls clearer and your internet faster. 2. How does the 3G & Calls booster work? - The 3G & Calls booster works by picking up weak mobile signals from outside, then amplifying those signals. It operates on 900MHz and 2100MHz frequencies, which are used by mobile networks in Brazil. The boosted signal covers an area of up to 1,000 square meters, helping everyone in that space have better phone reception. 3. Is the booster compatible with all networks? - Yes, the 3G & Calls booster is designed to work with all 3G mobile networks in Brazil. It can boost signals from different carriers, including Oi and Algar, which means you don’t have to worry if everyone in your home is using a different service provider. 4. Can the booster create a signal? - No, the booster cannot create a signal. It can only amplify an existing one. So, if there are no signals reaching the outside of your home, the booster won’t work. It’s important to have some external signal for it to function effectively. 5. How can I check my phone's signal frequency band? - You can check your phone's frequency band by dialing \*3001#12345#\* on your iPhone and pressing the call button. Then, look for 'Serving Cell Info' and find the 'Freq Band Indicator' to see if it shows band 8 or 1, which are used by the booster. 6. What is included in the booster kit? - The booster kit includes everything you need for installation: an external antenna to capture the signal, cables, the booster unit itself, an indoor antenna to spread the signal, and a power adapter. This means you get everything in one package for easy setup. 7. How does the booster help with calls and texts? - The booster improves your phone signals, which means you can make and receive calls without worrying about dropped calls. It also boosts your ability to send and receive text messages, making communication smoother and more reliable. 8. What areas can benefit from using the booster? - The booster covers a large area of up to 1,000 square meters, making it suitable for big houses, offices, hotels, warehouses, and other large spaces. If you have weak signals in these areas, the booster can significantly enhance your reception. 9. Can I upgrade certain components of the booster? - Yes, you can upgrade certain parts of the booster system! Options include upgrading the external cables for longer reach or swapping the outdoor antenna for a higher gain model, which can improve performance if your phone shows only one or two signal bars.
