my 9 y old has had a monthly mobile contract since he was 3
it started off being needed for disabilities as he needs to watch videos or listen to music with head phones on while out a he cant cope outside
then at 6 it was used for home educational purposes at home and out and about
he takes photos and videos when out,if we talk about a subject he googles it and if you use the speech bit google reads it out to you
he has a new model ever 2 years atm he has a p20 ad he looks after it
,hes never dropped it or lost it
he obviously has no social media,he cant read full or write at all (mentally 5)so hes cant search or come across inappropriate stuff with out me hearing him,he uses google speech search for what he wants to search for and as hes with us 24/7(needs constant supervision because of disabilities)we know what hes doing
besides hes semi verbal so only used a few words a time
and he had only family as contacts
alexa and google has helped him to learn to read a bit and recognize letters
so used the right way phones can be a great asset to kids if its supervised
its not all social media and inappropriate websites
