Since 2005, rates to send and receive text messages on all four major carrier networks have doubled from 10 cents to 20 cents per message. If the same pricing was applied on a per-byte basis to a single MP3 song download, it would set you back almost $24,000 according to one estimate. So why are carriers gouging their customers so? Because they can, concludes Reardon."
