What defines a Flash Message, and how does it differ from standard SMS?

A Flash Message is a type of SMS that appears instantly on a recipient’s screen without needing to be opened, often disappearing after display (e.g., “Emergency: Power outage at 5 PM -SMSGAT”). Unlike standard SMS, which sit in the inbox until read, Flash Messages are ideal for urgent alerts. SMSGatewayCenter supports Flash SMS via our SMS gateway, perfect for time-sensitive notifications.
