to configure GPRS (or other data channel)
settings to his/her phone

phone number or an e-mail address
The messages are always relayed through a
MMSC (Multimedia Messaging Service

ISP’s have personal accounts for users
People can for example store pictures on an ISP’s
server and then send them as an MMS using a
computer
Future MMS services
Every possible way of combining text, sound
and pictures
