How to Send Free SMS Online

1. Locate the number you wish to send an SMS to. Since you will be sending a message from a browser, you'll be unable to pull numbers directly from your contact list. Also figure out what carrier your recipient uses.
2. Find a website that allows you to send a message for free. There are many different types of sites, but a few allow you to send messages for free, and to multiple carriers. A popular website that offers this service is onlinetextmessage.com.
3. Input the number you wish to send a message to, your own information if necessary, and any other required information. Select the appropriate carrier, then send your message. The phone number you typed in will receive your text message.
