I think, the most easiest is to do it with Siemens mobile, because they use asynchronous serial communication. Nokias use FBUS/MBUS, a little bit complicated.
You can find all you need about SMS in the book entitled "Mobile Application Development with SMS and the SIM Toolkit" by Scott B. Guthery and Mary J. Cronin.
Unfortunatelly I could not attach it here but if you need send me request via e-mail and I will send you pdf version of this book.

You can do UART communication using 16F84. You will have to use bitbanging technique and 16F84 running at 4 MHZ, you cannot achieve good communication above 9600 baud. I would suggest you to use 16F628A which has an internal UART. Typically the default baud rated of the mobile phones are 19200 baud.
1st---what phone or modem u want use.
2nd---the phone or modem must have at command
3rd--- if use PIC16F84A must use 8Mhz because the speed.
4th--- what languase u want use.(MPLAB,PIC BASIC PRO,C,PROTON)
5----- u must know about serial comunication.
