How to Send a SMS Text from Yahoo! Mail

1. Log into your Yahoo! mail account.
2. Click the 'New' button to compose a new message.
3. Type the recipient's ten-digit phone number, followed by the SMS gateway. (For example, AT&T uses @txt.att.net, and Verizon uses @vtext.com.)
4. Type your message in the text field as you normally would. Some phones can receive texts of only 160 characters or less. Keep this in mind while typing your message.
5. Click the 'Send' button to send your message.
