Senator Herb Kohl

chairman of the Senate antitrust subcommittee

was curious about the doubling of prices for text messages charged by the major American carriers from 2005 to 2008

All four of the major carriers decided during the last three years to increase the pay-per-use price for messages to 20 cents from 10 cents

2.5 trillion sent messages this year

is up 32 percent from 2007

3.3 trillion messages to be sent in 2009

20 class-action lawsuits have been filed around the country

alleging price-fixing for text messaging services

T-Mobile and AT&T contended

pay-per-use price of a message is

unimportant because most messaging is done as part of a package

text messages are not just tiny; they are also free riders, tucked into

space reserved for operation of the wireless network

The channel uses space whether or not a text message is inserted

Customers with unlimited plans

might think they’re getting the best out of the arrangement

But the carriers

can provide unlimited quantities

no cost to themselves
