MMS is an extension of SMS that enables the transmission of multimedia content, such as images, audio, video, and text. The primary difference between SMS and MMS is that MMS supports a much wider range of content types and allows for longer text messages. While SMS is limited to 160 characters, MMS can contain up to 1530 characters, and special characters do not impact this limit.
MMS lets you send text, pictures, animations, and short videos. You can include images in JPG, PNG, or GIF format—up to 600 KB in size—to make your messages more engaging.
Leveraging MMS, you can engage your audience with dynamic and visually appealing messages, enhancing the overall impact of the marketing efforts.
