On the Messaging screen, tap the New message icon at the top right corner of the screen.
Add the recipient(s).
If more than one recipient is entered, you will be asked to choose between a group conversation and an individual message.
Tap Group Conversation to allow all of the recipients to be viewed by each other so they can respond to you and the group. The message is sent as a multimedia message (MMS).
Tap Individual Message so that none of the recipients can see the other recipients (similar to BCC). Each individual can only respond to you.
Complete the message as necessary, then tap Send to all.
