Can I still trigger an alert in areas with poor cell coverage?

How POM Mobile minimizes needed bandwidth for alerts

To maximize the POM Mobile's ability to send alerts, even in areas with poor cell coverage, it uses AT&T's LTE-M network and small data packets for alert information. Also, the emergency dispatch is trained to send emergency services immediately if they cannot reach a user on their POM Mobile device, so even if the call can't go through because of bad coverage, the user will still receive help.
