I'm a bit of a technophobe & I don't have a mobile myself: I do worry about possible health risks & also wonder how something can go from being non-existent to totally essential in just a few years. Dd does go to school on the bus, but children always managed to do this before mobiles were invented, so I can't really see the need - they just seem like another expense, which could be stolen, lost or cause health problems. And before anyone wonders, I'm not a troll & this is a serious question. Fwiw, she has one friend who has no phone, & at one of the other schools in our town where some of her friends go children are not allowed mobiles.
