hello all
I want to attach my gsm shield to arduino
but its pin is different from diferente Arduino GSM shield pins and I dont know how attach it
this is my shield picture
can you help me?

Have you already checked this site? Here you can find a bunch of documentations, e.g. AT command reference as well as some hints on the pin layout in the comments section.

I read this site but I didnt understand any thing .
I dont know which pin of shield athach to pins of arduino.
isnt any help?

Quote from the site mentioned above:

as shown in this picture it has tho important sections named GSM and MCU,

each one has 4 pins

Vcc,GND,M-T(transmit),M-R(receive) for MCU

and Vcc,GND,G-T(transmit),G-R(receive) for GSM

You have to connect the Transmit lines of the GSM module to the Recive pins of your UART pins on the Arduino. If you are using the standard hardware serial/UART interface of the Arduino Uno this would be pin 0 (labeled with RX). The Receive pin should be connected with the Transmit pin (by default pin 1 TX).
Please be aware that (as far as I have seen) the module is using 3.3v, this could also mean you have to level shift the MCU TX pin from 5 to 3.3V using for example a simple voltage divider. Otherwise, if putting 5V to the GSM board, it could fry, if the pins are not 5V tolerant.
