No R-rated mobile content on their watch.
American operator AT&T and researcher GfK are behind the data, which shows an overwhelming 90 per cent of eight-17 year-olds are happy for parents to set rules on their mobile activity, though just two-thirds of parents have implemented such restrictions.
It shows that the laidback 24 per cent that haven't enforced parental guidance are missing a trick, as 39 per cent of 12-14 year olds know someone that's been sent a sext – text of a sexual nature. This leaps to 53 per cent for 15-17 year olds.
Meanwhile, almost one-fifth of eight-11 year olds have been on the receiving end of text-based bullying, and kids say mobile safety isn't high on parents' priority lists.
Betsy Landers, National PTA president, said: "Today's parent should be aware of today's technology and how it can affect their children. Being an engaged parent includes having a conversation about wireless safety with their children as they grow up."
The results show the average age for a child to receive their first mobile is 12.1, with the age creeping to 13.8 for smartphones.
58 per cent of parents say their network provider offers monitoring tools for parents to manage security, safety etc, though one in seven say they're unsure whether they have access to such a platform.
Janiece Evans-Page, assistant VP - community engagement, AT&T, said: "The fact is, there are a variety of free to low-cost tools that can give parents peace of mind, and we want 100 percent of the parents out there to know their options - not just 58 per cent of them."
