Why do you need a signal booster ?

Cell Phones have become an indispensable part of modern day lives. From our first breath to our last in the day, we ensure we keep our cell phone close. The cell phone alone is not what fancies us. There’s constant need to stay connected, the fear of “losing out” in life or being “left behind”, better known as nomophobia. Although technology has progressed immensely in helping the signal reception reach our doorstep, that is not always the case - Voices are not always quite clear to be comprehensible, mobile internet becomes sluggish and seems to take forever to load Internet pages or Youtube videos due to weak signal, and the worst is the problem of dropped calls altogether.
