How to Text a Cell Phone From Your Computer

1. Open your email client software on your computer or log in to your online email service.
2. Open a new message composition window.
3. Enter the recipient's text address in the To field. This address is the 10-digit phone number without dashes, followed by '@' and the cellular provider's messaging domain. As an example, to send a message to the T-Mobile number 555-555-5555, enter '5555555555@tmomail.net' in the To field. Some of the more common provider addresses are:Alltel: ...@message.alltel.com
Cingular AT&T: ...@txt.att.net
Boost Mobile: ...@myboostmobile.com
Cricket: ...@mms.mycricket.com
Nextel: ...@messaging.nextel.com
Rogers: ...@pcs.rogers.com
T-Mobile: ...@tmomail.net
Verizon: ...@vtext.com
Virgin Mobile: ...@vmobl.comIf your recipient's messaging domain isn't on the list, contact the provider for the information.
4. Enter a message in the body of the email. The length of the message varies among providers, but is typically between 125 and 185 characters, including the email address. Some cellular providers allow picture attachments, but they may require the recipient to access a Web page to view any attachment; some providers do not support multimedia email-to-SMS at all.
5. Send the email as you normally would.
