Multimedia Messaging Service, also known as picture messaging.  This service is used to send pictures, sound clips, SMS messages that are over 160 characters and group messages to other cellular phones. Access to the cellular data network is a requirement for sending and receiving messages and requires a data package. The size and quality of MMS messages can be limited by both the network and the sending/receiving devices. If the phone is unable to retrieve the MMS message, an SMS message will be sent from sender 3351 or sender 3352 with directions to visit the zsend website to view the MMS message. A code will be provided and the link is good for 7 days.

If I have a camera phone, do I need a data plan to use the picture/camera features? To take a picture you do not need a special plan, however to send or receive an MMS message, a data package is required.
