Relating to content filters provided by Internet service providers.

HB 4189 requires Texas internet service providers (ISPs) to offer customers a free, optional content filter that blocks access to explicit material defined as visual depictions of sexual conduct or intimate body parts. The filter must prevent customers from accessing such material when enabled and notify them when blocking occurs. It directly affects all Texas customers who subscribe to internet service, giving them the choice to activate the filter at no additional cost. The bill takes effect September 1, 2025, and does not mandate filters but requires ISPs to make them available.
