India now has over 400 million mobile phone users. Three out of five phone users of India do not use SMS for several reasons, one of which is their inability or unfamiliarity to typing in English, another being the relative high cost of SMS, when voice is cheap and finally the cumbersome nature of typing an SMS that has remained complex outside specific age and social groups. There are many occassions when an SMS does what a voice call cannot do. Everybody would gain from the ability of using SMS easily and by everyone, including new applications that would become possible.

Although some kind of support to type in Hindi in some of the phones introduced in recent time has been included, the usability of multitapping, where the user is expected to tap several times (upto 9 times) in rapid succession in order to type one character has remained unpopular. A related problem is it is impossible to print all the multiple characters of Indian language on the limited space on the face of the key and hence the user is also expected to reckon the varnamala while typing. This is quite an unusable system and SMS usage in Hindi has never taken off. Also, even if Hindi is included on the face of the keypad, it would be impossible to accomodate the other Indian languages on the same keypad.

An approach was taken which did not rely on printed characters on the keypad but instead are shown on the screen. And to develop an usability that kept the number of keystrokes required to the minimum. And hence the Basic mode was developed at first.

With further exploration, and some serendipidity, a totally lateral approach to typing using the statistical nature of languages to make a prediction was developed. With dynamic allocation of keys, it was also given an innovative twist of ergonomicity, (because not all the keys are equally comfortable to your thumb). The statistical approach, apart from being lightweight offered many advantages over a dictionary based system.

And finally we have CleverTexting, (patent applied), which is a dictionaryless technology which places characters to positions comfortable to your texting thumb by predicting from the statistical nature of a particular language mined from large amounts of text corpuses.

SMS Compression - a worlds first was also added to it to increase the payload of the Indian language SMS from 70 characters per SMS to about 200.
