Send text messages from a computer with Google Voice, Skype, Yahoo! Messenger or an email-to-SMS gateway. The programs are compatible with both PC and Mac computers and let you use a keyboard to type messages.
People can sign up for Google Voice for free. The program gives users a phone number for voice calls and text messages. It also has an option to forward incoming messages to another phone number. Sending text messages is free in the United States and Canada.
Skype offers a text message service for a fee. People who purchase Skype credits can send text messages directly from the program.
Email-to-SMS gateways enable people to send text messages with email. Some carriers that offer this service include AT&T Mobility and Verizon Wireless.
