MMS stands for Multimedia Messaging Service. It is a standard way to send messages that include multimedia content such as images, videos, audio files, emojis, and website links over a cellular network. Unlike SMS (Short Message Service), which is limited to text messages of up to 160 characters, MMS allows richer content to be shared, including photos, videos, audio clips, and longer text messages

. MMS messages are transmitted differently from SMS. When you send an MMS, the multimedia content is encoded and sent to the carrier's Multimedia Messaging Service Center (MMSC), which then forwards it to the recipient's MMSC if they are on a different carrier. The recipient's device retrieves the multimedia content via a URL sent in a control message

. MMS is widely used for personal communication to share rich media and is also leveraged by businesses for marketing, customer communication, and sharing detailed information like product images, videos, and documents

. In summary, MMS messages are enhanced text messages that go beyond plain text by including multimedia elements, making communication more engaging and informative
