Just to clarify, Ijaz means don't write your posts here (or on any other professional forum) like an SMS message; eg, write "messages" and "and" and "please" intead of just "msgs" and "n" and "plz".

He is not saying that SMS is necessarily a bad solution for your GSM communications in your project!

If you want people to make the effort to answer your questions here, it pays to show that you have made some effort yourself in posting the question - excessive abbreviation just makes the post harder to read, and looks lazy.
