Public schools; require school boards to adopt policy on bell-to-bell cell phone prohibition.

HB 818 requires Mississippi public school districts to create and implement age-appropriate policies restricting student cell phone use from the start to end of the school day ("bell-to-bell"). The bill mandates that phones be stored (not carried) during instructional time, prohibits suspensions or expulsions for violations, and bans social media access via school networks. Exceptions allow phones for students with health needs or IEPs. This directly affects all K-12 public school students and requires school boards to publicly post these policies.
