Does anyone know of systems where you can have a basic phone with just one number on it? Got a situation with a 12 and 13 year old (not mine) that have smart phones that they are literally addicted to, see inappropriate things on from their friends, lie about and they generally cause problems - they have been warned they will be taken away and given cheapo phones instead. Has anyone had experience of this? Just want them to be able to contact home and thats it basically and limit the money they spend.
