Alerts sent may not be delivered if the mobile phone is not in range of a transmission site, or if sufficient network capacity is not available at a particular time. Even within a coverage area, factors beyond the control of the wireless carrier may interfere with message delivery, including the customer's equipment, terrain, proximity to buildings, foliage, and weather. The wireless carrier does not guarantee that alerts will be delivered and will not be liable for delayed or undelivered messages.
