Google has launched its free SMS service in India and other countries using which users can send SMS to people who are in their contact list for free. Google has reported saying that it will not charge for SMS but initially users will be provided with 50 free SMSes. Google would decrease this count by one everytime you send a SMS but the good thing is that when a user responds to text message, the count increases by 5.
If SMS count becomes 0(zero), it would ideally reset within 24hours or the user can buy the credit by paying for the service.
This service went live in India and other 51 countries on October 10th. Google has also provided service where-in the user can block receiving messages sent from Google SMS chat.
