What is Multimedia Message Service
Multimedia Message Service (MMS) extends the capabilities of Alibaba Cloud Short Message Service (SMS). It includes three types of messages, digital message, card message, and 5G message, that support multimedia content like images, audio, and videos, as well as an interactive menu. This makes MMS ideal for scenarios that require rich media displays and user interaction.
