Ok. fine. Now, I can understand your requirement clearly. You can select the PIC MCU with the USART capability for your project. For example PIC16F628A. If you want to select any other PIC, it is no problem but ensure USART is there. It is up to you. Also, you have to select MAX232 (if +5v supply available). But, you are going to use only 3.6v/3.7v in your project. So, you can select any of MAX3222/MAX3232/MAX3237/MAX3241 IC to communicate the GSM Modem from PIC MCU thro' PIC's USART Ports.

If space is constraint, you can select appropriate package like SOP, MSOP etc.
Connect PIC MCU to GSM Modem (Serial Port) thro' USART Ports. If you need help on schematic, let me know.
