hello sir,
we want to know about, can we communicate any micro controller device with sim800 modem without changing any software program of micro controller device.
 

Yes, if MCU has sufficient RAM for uart buffer to hold 180 bytes, the length of an SMS.

I have used SIM800H with PIC18F.

More than curious with the question I'm amazed with the answer.
All modems sold with the SIM800 have serial interface.
Do not make assumptions.
