Cell location information; require wireless service providers to disclose to law enforcement under certain circumstances.

HB 1055 requires Mississippi wireless service providers to share a customer's real-time cell location with police or 911 centers only during emergencies involving risk of death or serious physical harm. It prohibits lawsuits against providers who disclose location data in good faith under this law and allows providers to create voluntary protocols for sharing location information. The law applies to all wireless companies operating in Mississippi and mandates the state Department of Public Safety to collect provider contact details for emergency requests. It does not permit location disclosures for routine investigations or non-emergency situations.
