What is the major advantage of SMS/MMS as a communication channel?

The major advantage of SMS/MMS as a communication channel lies in its fast message delivery. SMS (Short Message Service) and MMS (Multimedia Messaging Service) are designed to transmit messages quickly over mobile networks, allowing for immediate communication. This immediacy is particularly valuable in scenarios where timely information is crucial, such as sending alerts, reminders, or customer service notifications.

The efficiency of these channels in reaching the recipient instantly enhances user engagement and ensures that important messages are received without significant delays. While other factors such as content richness or cost may have their own relevance, the speed at which SMS/MMS can deliver messages is often a defining characteristic that sets it apart from other communication methods.
