But it costs extra credits... If you choose to send a MMS message (Multimedia Messaging Service... for all you acronym amateurs), your message will cost 6 text credits per recipient.
(6x the credits of a normal text)
FYI: When you do send a MMS message the text message is sent from a different number.
Using MMS you are allowed to send text pictures, videos, and long text messages (up to 500 characters).
