Hop-On just launched a disposable mobile phone. Hop-On's new Hop1800 phone is not only dirt cheap, costing just $10 USD, but also the company is offering a $5 rebate for returning the phone to encourage recycling. The pre-paid HOP1800 cellphone has no bells and whistles, it's just a basic celly with no screen that simply makes phone calls. Nothing more, nothing less. However it will only be sold in US retail and convenience stalls.
