The T-Mobile have this pay by the day prepaid promo which a subscriber doesn't have to have a carrier contract with them and they only charge as low as $1 per day when the mobile is used.
Plus it also includes an unlimited call from 7pm to 7am to any T-Mobile number. You are also entitled to nationwide roaming on the T-mobile USA network; you can also use t-zones.
