How young is too young to have a cell phone?

How young is too young to have a cell phone? Many older Millennials got their first phones in high school, but as the technology has become more ubiquitous, the age at which kids are given a phone has gotten progressively younger. According to a recent survey, 64% of parents say they’d buy their child a cell phone between the ages of 10 and 14, and 10% said “younger than 10.” (Jezebel)
