Even though text messaging is typically a phone-to-phone communication medium, nowadays a lot of people prefer sending messages from the computer. For one, sending messages from the computer doesn't cost you a cent and you get to send multiple text messages to multiple recipients. It is also simpler and quicker to type the entire message using a computer keyboard compared with your cellphone's keypad. Websites such as Free SMS, Sea SMS and Text Em allow you to send bulk SMS for free.
Navigate your Web browser to any of these websites: Free SMS, Sea SMS or Text Em (see Resources).
Enter the recipient's cell phone number in the respective field. If the websites asks, specify the recipient's country.
Type your message in the message box.
Click on "Send Message." Your SMS will be delivered to the recipient.
