The $10 disposable cellphone – the HOP1800
A company called Hop-On has just launched a disposable cellphone, the HOP1800.

This disposable cellphone will sell for $10, all you need to do is add a sim card, and you can add one from over 40 domestic carriers within the US
The Hop1800 is a basic phone, with no display, no mp3 or video playback, so basically it is a basic phone and thats it.
There are two versions available covering 850/1900 and 900/1800 bands and battery life is 4 hours of talk time and 150 hours of standby.
The Hop1800 will go on sale in US retail and convenience stores, and if you want to return it after you have used it you will get a $5 ‘Go Green’ rebate.

Sounds like something that could be useful to tourists and in emergencies if it came packaged with a pay as you go sim and talktime
