San Francisco Unified School District phone policy under California law, serving ~49,000 students in San Francisco Bay Area. California's Phone-Free School Act requires every district, COE, and charter to adopt a smartphone-restriction policy by July 1, 2026. Enforcement models, costs, and complianc
San Francisco Unified School District is a public school district headquartered in San Francisco, California (City and County of San Francisco), serving approximately 49,000 students across the San Francisco Bay Area area. Like every district in California, its cell phone rules are shaped by state law — and by how well the policy is actually enforced on each campus.
Does SFUSD ban cell phones?
Yes. California law (AB 3216 (2024) — Phone-Free School Act) requires districts to restrict student personal-device use during the school day, so the district must adopt and enforce a written phone policy.

Enforcing a phone-free day across San Francisco Bay Area
California leaves the enforcement method to local districts. The schools that succeed pair the policy with a mechanism that doesn't put the burden on teachers and that produces compliance data when the state asks. At 49,000 students, SFUSD's scale is exactly where the enforcement method matters most: a policy that works in one classroom has to work across dozens of campuses at once.
Three enforcement models districts choose from
- • Physical pouches (e.g., Yondr): a per-student cost that recurs as pouches are lost or damaged, plus daily distribution and unlocking logistics multiplied by every campus — and little compliance data.
- • District storage (lockers, caddies, classroom bins): low hardware cost, but it relies on staff to police compliance period after period.
- • Device-level software (LockedIn): OS-level locking, campus geofencing, and automated reporting — deployed identically to every school in the district with no daily logistics.
LockedIn is a software-based phone-free campus solution built for districts like SFUSD. It locks student phones at the operating-system level on the devices students already carry, ties enforcement to school hours and campus geofences, and gives administrators a live dashboard plus automated compliance reports — exactly what a California district needs to show enforcement is real. There's no hardware to ship, lose, or replace across San Francisco Bay Area.
