There are several free texting sites that you can use to send texts online. txt2day.com, 811.com, and text4free.net are only a few of the sites available. The process is fairly simple. You enter in the phone number of the person you want to text, their cell carrier if you have it, and a short message. Be aware, these services log your IP address, so don’t send anything you wouldn’t want traced back to you!
