Today’s cell phones come equipped with 3G connectivity. This refers to the speed at which data can be downloaded and uploaded on your cell phone. If your 3G enabled phone is slow downloading and uploading, or if you are constantly losing signal, you should get a 3G booster. 3G boosters are often used in places of business or in residential homes. A 3G booster will amplify your signal so you have a stronger more reliable connection to the cell phone tower. If you’re computer or cell phone is operating at a slow pace a 3G booster is what you need.
