AA message （Gexin）is a phone number based IM (instant messaging) service that allows users to send message and multimedia-message even voices for free. On Gexin’s platform, after installing a small app on your mobile phone, you could easily send SMS from website to all your friends in your contact list (they don't have to install Gexin), and the beautiful thing is that if your friend also installed Gexin, all SMS between you two would become free. From today on, you could throw off those small and jam phone keyboard and choose to type SMS cozily on a laptop or on an iPad instead.
