MMS or Multimedia Messaging Service is a standard for telephone messaging systems that allows sending messages that include multimedia objects (images, audio, video, rich text) and not just text as in Short Message Service (SMS).
If you have a phone that plays video and an MMS Plan with your mobile provider you are ready to send Beemas via MMS. Of course the person to whom you send your MMS must also have a phone that can play video (Blackberries don't play video) and an MMS plan. If you have been able to send pictures or videos to your friends in the past you will be able to send Beemas as they are just a standard video file.
Every phone is different so the process for sending an MMS will be different for everyone. However, at the very basic level there are two ways that most phones handle the creation of an MMS message.
1 - Create an ordinary SMS or Text Message and attach a file, in this case your Beema, and send to your friend's mobile number.
2 - While viewing the Beema you have downloaded onto your phone select the 'Send Video' option (if your phone has this option) and then choose MMS from the sending options, enter your friend's mobile number and hit send.
