A class action lawsuit has been filed against three cell phone service providers that are charging Missouri customers extra for 911 service that isn’t available. The St. Louis Post-Dispatch reports two consumers have filed the suit against Nextel, Alltel and Sprint. The suit claims the company bills are misleading and that consumers are being forced to pay for service they aren’t getting. The companies say they are responding to federal pressure to provide emergency phone service for cell phones, such as informing the emergency center the cell phone number and the location of the caller – something available for traditional phones, but not now available for the cell phone user. The state of Missouri does not yet have the technology available to track 911 cell calls.
