For people who send sms:
SMS xxs you can compress your sms by removing space and by using slang abbreviation.
For people who receive sms and cant understand slang or no-space sms they can paste the text into SMS xxs for translating it into normal plain understable text.
the abbreviations are editable.
Waiting for review ver. 1.1. that correct the slang button bug for all countries (US and Italy works fine now).
