When the iPhone received its 3.0 firmware upgrade, access to Multimedia Messaging Services, or MMS, was introduced. This is an extension of SMS text messaging and is a standardized platform for sending and receiving messages with multimedia content attached on a cell phone. The iPhone is able to send photos, videos, text and audio files via its MMS application, as well as receive similar content from other iPhones and cell phones.
Launch the "Messages" application on the iPhone.
Tap the square icon in the upper-right corner to compose a new message.
Enter the recipient in the To field either by typing in his cell phone number or tapping the blue "+" button to select him from the iPhone's address book.
Type your text message into the text field.
Tap the "Camera" button to the left of the text field to either capture a new photo or video or to select an existing one already stored on the iPhone.
Tap the "Send" button when the message and its attachments are ready.
- Until you add a video, photo or audio clip, the iPhone sends the message as a standard SMS text. It automatically changes it to an MMS when multimedia content is attached.
