The modular cell phone storage locker may comprise a cabinet with one or more doors. The interior space of the cabin may comprise one or more internal compartments defined by the exterior walls of the cabinet and internal dividers. A charging port and a disinfecting device may be located within each compartment. The doors may be prevented from opening by a lock, which is responsive to a timer. Locked periods and unlocked periods may be defined through a keypad on an operator panel. While locked, cell phones left in a compartment may be recharged and disinfected. A software application on the phone may prevent usage of the phone and modify phone operation during locked periods. One or more time displays visible on the exterior of the cabinet may display information pertinent to the operation of the timer. A fingerprint reader may allow administrator access to the lock.
