but it’s showing me errors…Please suggest me the solution

Read the sticky posts at the start, modify that post and then we can talk.

But you don’t want to share them?

Please, read Mike’s reply, and act on it.

Edit: let me guess:

#include <SoftwareSerial.h>
SoftwareSerial gsmSerial(ARDUINORX, ARDUINOTX);

Please read the sticky topic at the top of this section, and act on what you have read there.

Grumpy_Mike:
Read the sticky posts at the start, modify that post and then we can talk.

Still waiting. Do you put smiles in your code? I am sure the compiler would complain.

HI,

I HAVE ATTACHED THE WORD FILE CONTAINING 2 CODES

So you can not be bothered to read the sticky and edit your two previous posts so they conform. So why pray tell do you expect help. This has shown either total arrogance, or so much ignorance that it is doubtful if you can ever understand the reply.
Third strike - your out from me.

Hi darshika!, I just wanna ask, what if your GSM is preffered to send it to different phone numbers not declared in the sketch? coz my project is also using a gsm, rfid reader, database and arduino mega; but i have different receiver of message each time i swipe a rfid card to a reader..please teach me how to configure your sketch in GSM..
