Enhanced Message Service (EMS) is an extension of Short Messaging Service (SMS) that enables users to send formatted text, images, animations, and sound within messages. EMS messages are built on SMS and typically consist of multiple SMS messages. These messages can include text, images, animations, and sound. Images and animations in EMS have a standard size of 96 × 32 pixels. To send and receive EMS messages, users need a compatible phone, and no network enhancements are required.
