Exchanging messages
You can send text (SMS) messages of up to 160 characters to another mobile phone.
If you keep typing after the limit, your message is delivered as a series of messages.
Multimedia (MMS) messages can contain text and a picture, a recorded voice, an
audio file, a video, or a picture slideshow.
Messaging automatically converts a message into a multimedia message if you send
it to an email address instead of a phone number, add a subject, or attach a media file.
