An influential senator wants to take a closer look at charges for text messages.
Most teens typing messages to their friends don't care how much it costs. But Sen. Herb Kohl, a key member of the Senate Judiciary Committee, is crying foul.
The Wisconsin Democrat sent a letter through the mail to the top four cell phone companies in the U.S. demanding answers for their high text messaging rates. He says each company seems to have changed its rate at the same time to the same price.
The price has increased 100 percent since 2005. Just a few years ago it cost 10 cents per text message. It now costs 20 cents, but customers still only can type 160 characters per text.
The companies contacted--Verizon Wireless, AT&T Inc., Sprint Nextel Corp. and T-Mobile--planned to respond to the senator's letter.
