The phones, made by a company called Hop-On, only allow users to make outgoing calls and are no use for text messaging, but they cost much less than normal phones.
For around £21 buyers get an hours worth of airtime, and they don't even have to dial a number.
Price cut if you recycle
Instead you just press the call button and tell an operator what number you want. They then connect you to who you want to call.
And for those of you worried about thousands of the new phones littering the country, the makers are giving out a discount if you hand in your old handset when it's out of airtime..
