the sim300 generally has both TTL and RS232 serial interfaces - if so you should be able to interface directly to a micro without the need of using a MAX232

have a look at this thread

yes u can directly connect with PC with RS-232 interface or connect it to controller directly from GSM processor to controller.
but u will need voltage converter in between.

if you use low voltage level then voltage converter is needed.
