Organizers have contacted cell service providers to make sure smartphones will have access during the event. AT&T has committed to extra portable cell towers.
Social media has helped drive the national marches in Atlanta, Washington and multiple other cities. Participants are using hashtags and other designators for staying in touch and showing their support. A special Snapchat filter will be accessible. And those sharing photos and videos will be using the hashtags #MFOLGeorgia, #WhyIMarch, #EnoughIsEnough, #EndGunViolence and #NeverAgain.
