Arduino GSM example for SM5100B shield

I have this shield based on SM5100B chipset. https://www.sparkfun.com/products/9607

Do you know if the arduino's examples for sending SMS will work with this shield/chipset?

If you look at the Hayes AT command set available on the link you quoted, it is in common with most if not all GSM Modems, the industry standard interface..

So just google aruino -- send sms and experiment..
