Gmail, providing a huge, free web storage space, has already offered lots of features in the desktop and the mobile edition as well. The latest feature from Gooel, Gmail SMS Chat, allows us to send shirt text messages to our contacts. The service - just like lots of other features - can be turned on in the Gmail settings, on the Labs tab, although it is currently available only for US residents. After enabling the feature we can send SMS messages to contacts. Upon successfully sending the first message Google attaches a 406 number to our Gmail account, so the addressee can easily identify the sender.
