Ways to Send Free SMS

Sending Through Email
Online free SMS services often use email to send the free SMS to the phone or email address of the recipient. The service works by filling in the recipient email address or phone number and then typing the short message and pressing send. The sender uses an online website through a computer to send the message from the service. There are a few free services available through the website that allow free SMS sending such as Teleflip.com.
Sending Through Instant Messengers
Instant messengers, such as AIM, MSN Messenger and Yahoo Messenger, are a free way to send SMS from a computer to a phone. These work by opening a new message box without the contact entered. Instead of an IM name, type in the phone number with area code in the contact name. Type the message and press 'Send' and the recipient will get the message.
Message Sending Websites
There are websites available, such as txtdrop.com, designed for sending free SMS messages. These services use advertisement to pay for the messages so that the user can send free SMS messages. Type in a personal email, the phone number of the recipient and the message and send the text to their phone. Some websites have conditions, such as a maximum word count or maximum number of SMS messages a day.
Personal Phone Service
Many phone services offer free text messaging or a specific number of free text messages a month. Conditions usually apply, such as services provided under a plan that works with specific phones rather than specific services, but there are options for free SMS through a cell phone provider.
