It is generally accepted that teens are allowed to use cellphones. In fact, smartphones have become an integral part of modern society and are widely used by people of all ages. Cellphones provide a convenient way for teens to stay in touch with family and friends, access information and entertainment, and stay organized.
That being said, it is important for parents and guardians to set boundaries and guidelines around cellphone use to ensure that it is safe and appropriate for their age and developmental stage. This can include setting limits on screen time, monitoring their online activity, and establishing rules around phone use during meal times, homework, or bedtime. It's important for parents to find a balance between allowing their teens to use cellphones and ensuring that they are using them responsibly.
