Hi Mohammed,

Screen, well its upto you.

MAX232 is basically a serial to ttl converter. Your controller can read only ttl logic. If your GSM module is communicating with RS232 serial standard, you need a RS232 to ttl converter. MAX232 will do this job.

If you share your circuit shcematic and details, we could help you more.
