I’m not sure if these Light Bulb Phone Charms are really essential, since setting your phone to silent mode with vibrate turned on is often more than enough to catch your attention whenever there’s an incoming call – still, I guess you might want to distract the rest of the cinema by telling them just how busy you are with this Light Bulb Phone Charm.
