How to Send a Text From My Computer

1. There are plenty of websites that allow you to send free SMS messages to most of the U.S. and some foreign providers. You can send the same message to several recipients, just type the message and click 'Send.' Most of such websites also allow sending pictures or videos. See links to examples in the 'References' section.
2. Yahoo! Messenger is a free instant messaging application by Yahoo! used for real-time conversations by users all over the globe. You can even call other computers or phones using VoIP (Voice over Internet Protocol). Text messaging to cellphones is also included and is free. Just select text option for your contact and click 'Send.' See the References section for link.
3. Skype is another application that uses VoIP, but unlike Yahoo! Messenger, it is not as convenient for instant messaging. Skype is a quick way to connect with friends via PC-to-PC calls with webcam and cell phone calls. Texting to phones is another feature of the application. However, there is a charge for this service.
