In the wake of Hurricane Harvey, wireless networks are experiencing outages, leaving some customers without reliable cellphone service. The four major providers are now stepping up to offer help by way of waiving service fees or offering extra data.

According to a report by the Federal Communication Commission [PDF], 320 of the 7,804 cell sites in the area are out of service, and at least 148,565 people living in hurricane-ravaged areas were without cable or wireline service on Sunday.
