Paranoid parents can keep an eye on their youngsters through the Vodafone Smart N9 Lite, a 4G smartphone geared toward safe usage on the web. Customised controls allow parents to disable or restrict access to the internet, and set daily time limits to games or social media. A Force Ring feature lets the mothers of Ireland summon their whippersnappers at full ring volume, even when the phone is on silent. A nightmare for kids, perhaps, but at only €89.99 for PAYG (or free on bill pay), no one will grumble. N9 Lite has 16GB of internal storage, 8MP rear-facing camera with flash, and a front-facing 5MP camera.
