SMS on a rotary phone eh?  That'll be your most processing intensive
portion of the PIC code.

The GSM module will have fairly simple methods to send text SMS,
similar to using a modem with AT command strings.  It's not difficult,
read up on the module's command manual.

The 18 series pic you mention should be fine.

Good luck!
