Communities utilizing EMMA whether it be your home community or a community out of your region any user enrolled in EMMA will receive alerts even when they go to another community. The alerts received are based off of your location you’re within; no more logging into many different applications or worrying about only being allowed up to a limited number of community alerts/regions. Once a user has EMMA on their mobile application, any public safety entity alert sent by Reverse 911 plans will be applicable to the EMMA user, regardless if they are on the registered list of local or guest users or not.  EMMA is intended to be a public safety alerting tool that is cross platform and cross geography but that listens for geographic GPS-enabled alerts relevant to that citizen as they travel the US.  This makes alerting signup easy for citizens and reduces the cost of engagement and outreach for administrators who are in charge of public safety.
