What is a cell phone signal booster? - A cell phone signal booster is a device that helps improve your phone's signal strength in areas where reception is weak. It takes the existing signal from outside and amplifies it, allowing you to make calls and use data more reliably. 2. How does the 3G - 2000m2 (Sercomtel) Cell Phone Signal Booster work? - This booster specifically enhances 3G signals on the 850MHz frequency, commonly used in Brazil.
