Whether or not you can connect into a celluar phone depends on the brand/model and carrier you are using, and how well they publish the ability to do so. Most people wanting cellualar communications find getting a cell phone module easier, and get a subscription with a carrier who permits the use of SIM cards. They program the SIM card with your phone number access info etc, then you plug the card into the celluar module you have purchased seperately. (www.sparkfun.com is one example of a company that provides cellular modules that accept SIM cards)

Try to stay away from sparkfun. I had nothing but trouble doing a bus. with them.

Go to http://www.roundsolutions.com/uk_products.htm. They have even better toys.

If the cellular phone has a modem interface, you can make the jump via another modem connected to the BasicStamp through everyday RS-232. It may be less elegant, less compact. But if you want to comprehent modem links, it is a useful study model.

This may not directly support SMS communicatons, but it has a lot of useful application opportunities.
