AT&T has launched a pay per use for those that have Cingular
Push To Talk phones. At $0.15 per minute with rounding to the next full
minute, the rate is best for those that would like to use the service
sparingly or more realistically, a way for AT&T to push more
customers (mind the pun) into using the service. Otherwise, customers
that want the service can pay $10 a month for unlimited access as well
as $20 dollars a month under a family plan for up to five lines.
