Will I receive an alert if I am offline?

You must have an active cellular or wifi connection to receive an alert. If you do not have an active or strong enough cellular or wifi connection when an alert is sent, the alert will be queued for a limited time and be sent to you once your device is connected, again. Examples of offline situations include the device being in airplane mode, cellular or wifi turned off, out of range of a local cellular tower or wifi base station, in dead zones where the cellular or wifi signal is impeded, etc.
