Hey hi! I think a few days back we had a CEan facing the same problem. Interfacing the micro controller to the mobile will require an interface of RS 232.You need to use the 'at' commands. Go through microcontroller books.Its easy if you get the right book.

You can test mobile with AT, it responds with OK

Then you can enable the text mode with AT+CMGF=1, to enable text mode and wait for OK.

Then at AT+CMGS="+91__________" ,fill in with phone number, you will get a > prompt and here put your message followed by ctrl+z.

If you get OK, your message will be tramsmitted.

You can use AT+CSQ to test signal strength.

I dont know why the link has been removed, but wait for it. I have asked the moderator.

And till you wait here, why dont you search google or some more sites before asking vague questions. Look into the matter and then formulate your problem. It will be easier to answer that way.
