Verizon Wireless is confirming that a substantial number of customers along the east coast of the United States may be affected by a significant service outage.

According to the outage map posted by DownDetector.com, the outage stretches as far west as Chicago and may interrupt service for customers in Central Lower Michigan.

Reports indicate that affected customers are unable to send text messages but can still make phone calls.

Verizon's customer service has confirmed the outage on Twitter, but does not have an estimated time for service restoration.
