If you put a small delay it will probably work

It whould help if you posted the code..

We are trying to help !

Well, what I see from the forst time it works is that there is almost 3 seconds between the command being sent and the data being received.  What delay are you using between your write and read?  You should start with significant delays to make sure things are working.  Since your code closes the port immediately after the read, you may be getting data that you do not see.  The serial port monitor program will not see data coming from the SIM after the port is closed.

The Program works fine.

Thanks to all
