There are no built-in facilities/APIs for sending/receiving encrypted SMS.

You have to have use your own encryptiong mechanism for the content before you send the SMS.

The receiving device must also run your application to decrypt the content.

If you want a secure mechanism, you must use one of the published public key algorithms and also have a secure key distribution mechanism.

For S60 2nd Edition based phones, at least, there are already existing apps that do this. For example this one:

You could also check http://www.bouncycastle.org/ for encryption library
