The Nokia 7210 Supernova is not as explosive as it sounds. In fact, it's as simple a phone as you can get these days.
With bright colours and basic features, it's well suited to be a pre-teen's first mobile. But a price tag of around £90 won't help the popularity of this unsophisticated handset.
Pressing the flesh
The 7210 is thin, at only 45 mm thick. We normally love a thin handset, but, combined with the 7210's flat keypad, it makes the phone hard to handle.
The keypad is totally flat, with raised ridges separating the rows of keys. Having featureless keys and raised strips that do nothing seems counter-intuitive. We also had to press the keys hard to get them to work, which made texting uncomfortable.
We also found the four-way navigation button too flush for easy pressing. From the home screen, each of the four directions can be programmed with a shortcut, which is handy because some features are a few clicks below the menu's surface. For example, the Flickr application is four menu levels down.
The 7210 felt flimsy and cheap to us. Removing the back plate to change the SIM card meant levering off a thin piece of plastic that felt as if it could snap in our hands.
The bold and the bland
The 51mm (2-inch) screen is small but clear, with a decent 240x320-pixel resolution. However, it only supports 262k colours, so it doesn't have the depth of a similar-sized screen, such as that of the .
