In the coming weeks and months, FEMA engineers will work with the FCC to produce a report detailing how successful the test was, and where the delivery may have failed and why. Simpson says the agencies will likely have a broad understanding of how well the test went within a few days.
FEMA wants to hear from people who had trouble receiving the alert. If you didn’t get it or if you received it multiple times, the agency asks you to email them at FEMA-National-Test@fema.dhs.gov. The IPAWS team wants to know the make and model of your phone, who your carrier is, whether your phone was in the same location for 30 minutes after the test, whether other people around you got the message, and whether you were using your phone at the time.
