How to Send Free SMS Text Messages Through My Gmail

Google's Gmail service provides email, chat and even SMS text messaging. While it is free for you to send SMS messages to your contacts' mobile phones, they are subject to the usual text-messaging charges from their service providers. Google places a limit of 50 SMS messages on your account. However, you earn the ability to send five more SMS messages each time someone replies to you.
