Why didn’t I get the latest test alert from my cellular provider?

The Alertable app is separate from the cellular broadcast technology that your cellular provider uses to send wireless alerts. You will need to contact your cellular provider to ask why you did not receive the test alert. In the meantime, the Alertable app provides a fallback option, as you should receive the alert in the app as long as you have a network connection (and are not offline or in airplane mode). And there is an Override Silent Mode setting so that you always hear critical alerts even if your phone volume is off or in do not disturb mode.
