Post your code please.

Hmm, wth no phone there is no help though.

You have to select a phone with Serial port like the old 6210, 6310 of Nokia with the appropriate serial cable. But nowadays I think it is a little difficult to find such a device.

May be you have to find a GSM module from an on-line shop (e-bay, sparkfun, digikey, etc)

Once I used the Wavecom and have to same they are very good.

About examples look at http://www.picbasic.co.uk/forum/showthread.php?t=3765

There is code available but for specific model.
