What is MMS?

MMS (Multimedia Messaging Service) is a messaging technology that allows users to send and receive messages containing multimedia content such as images, videos, audio files, and contact cards over a mobile network. Unlike plain text messages, MMS supports rich media formats and enables more dynamic communication between mobile devices.

Why use MMS?

MMS is a convenient way to:

  • Share rich media directly via text message without needing third-party apps.

  • Improve communication with visuals, especially for customer support, marketing, and real-time updates.

  • Reach users in regions where MMS is widely supported and used.
