Update (October 11, 2012): Well, it looks like Google has now extended the service to all mobile operators, after 8 months of the service going live in India. While there is still no official announcement from the company yet, the Google Chat support page has been updated to reflect this change. When we checked the service, we were able to send a text message to Airtel number, however we weren't able to send messages to a Vodafone number which is currently under DND (Do Not Disturb registry), and received an error message stating that the person did not receive the SMS. We feel Google should've devised a way to allow users to check whether a specific number is on DND or not, before sending the SMS. Also, it could have registered with the TRAI under the non-commercial communications services category for an exemption, similar to Jaxtr, Hike and others. Previously (March 9, 2012): Google seems to have silently expanded its Gmail SMS chat service to India, although we are not quite sure when it went live since there was no official announcement from the company. Not to be confused with Google's Push SMS service, which allows users to broadcast messages through channels, this service seems to be more focussed on one-to-one communication and allows Gmail and Google Apps users to send text messages through the Google Talk widget present in dashboard. How it works? One can enter the phone number they wish to send a message or select one of the existing contacts…
