To register with Tellit, you just have to connect through your Facebook or Google account. Also, the application can be synchronized to both your Twitter account and your contacts list, so you get all the contacts you want within seconds.
As usual with this kind of tool, Tellit has lots of icons and 'stickers' to add a touch of colour to your text messages. But even better is the ability to make voice calls from your Android, using 3G.
Tellit also allows you to create and manage chat groups for up to 100 people. It makes it possible to coordinate working groups easily.
Tellit is a very nice communication tool, which has arrived to give some real competition to the big players in the genre such as Whatsapp or LINE.
