Some reasons why you may not have gotten it:
Older phones may also not be compatible with Wireless Emergency Alerts, or WEA. Verizon has a list of phone models that are new enough to receive and display the alerts. For iPhones, for example, you’ll need an iPhone 4 or later to get any sort of alert. iPhones XR and later work with the latest version of WEA, which has improved geographic targeting in case of a real emergency.
If your cell coverage is from a smaller provider, they may also have opted out. “Some providers do not participate in WEA and will not transmit the national test,” FEMA says.
