This is a good question. I am skeptical as to how to answer this question. Let me put it this way. Yes, children can be allowed to use a regular phone(not a smartphone) because they need to be aware of some basic features such as making an emergency call or a text message. No, children should not be allowed to use a smartphone because it is highly addictive and it impacts the eyes. The internet is an ocean and it can easily distract children into trying out something unpleasant. Yes, technology has more positives but it should be taught to growing children at a particular age.
