Our friends basically locked down an old phone to just the apps they approve of. Their 8-year-old is home alone for about an hour after school, and they don't have a landline. We plugged in an old phone to a wall outlet, and just keep it locked with a pin. It allows for emergency calls. There is almost always someone home, so we don't feel the need to allow our kids to call us. Another set of friends trusts their 11-year-old with full access.
