How to Send Free SMS with Gmail?

If you are an avid internet user and relies heavily on gmail than a very good feature exists in form of ability to send sms right from gmail.

This feature is not available upfront and one need to activate the same by going to “Labs” section in Account settings. You will have to enable SMS service which will help you send sms to any person who might while chatting may get out of the internet connectivity.

Now add the contact number of the particular user you want to send the SMS to. First click on that person’s name on the Gmail chat window, and when a separate pop-up box opens, select “Send Text (SMS)” option: Enter the phone number and save: Now simply type the message, and send as SMS!

AS Per Google explanation regarding the service it reads as following:

SMS credit is an allocation of SMS (text messages) that you're able to send to a mobile phone:

• Initially, you're granted a credit of fifty messages.
• Every time you send a message, your credit decreases by one.
• Every time you receive an SMS message in Chat (for example when a phone user replies to one of your messages) your credit increases by five, up to a maximum of 50.

If your SMS credit goes down to zero at any point, it will increase back up to one 24 hours later. So, you won't ever be locked out of the system.

"Buying" additional messages

Keep in mind that if you'd like a higher message credit, you can always send an SMS to your own phone, and then reply to that message multiple times. Every time you send a reply message, your SMS credit is increased by five. Effectively, you're buying more messages by paying your phone company for these outgoing messages. 

Hope now you will not be out of communication even if the other party has gone off the internet connection and this service of a great use during chat when the other party gets out of the internet connectivity. You can send sms to a group by using the Google Free SMS channel and be in communication with your group free of cost.
