          ultra compact (28 x 22 mm) GSM/GPRS industrial wireless module

            support for both 900MHz and 1800MHz GSM frequencies

              standard AT instruction set (a very easy way to command&control the modem)

                integrated support of TCP/IP, http GET/POST, FTP and UDP data transfer protocols

                  low energy consumption (measured virtually zero wattage with 3.2 mA at 3.9 V, and 180 mA peaks during SMS sending)

                  accomodate any SIM card size (with a card adapter)

                  Firstly connect the grounds together and connect 5V to it (some voltage drop from the diode gets it to about what the spec wants, 3.3 - 4.5).

                  I also hooked it up to a FTDI breakout board so I could send and receive serial data (3.3V TX and RX).

                  I was just using the serial monitor within the Arduino IDE.  Set it to 57600 baud and also set the line ending to be a "Carriage Return" or "Both NL & CR".

                  Ground the BOOT pin momentarily to make it boot.  The boot LED flashed on and off steadily.

                  In the serial console it displays "MODEM:STARTUP" then eventually also displays "+PBREADY".

                  E.g.

                  MODEM:STARTUP
                  
                  +PBREADY
                  

                  At this point you can issue some basic AT commands to get some info about the module and SIM Card.

                  To get the IMEI number issue the command :AT+CGSN and it will respond with the IMEI and OK.  I changed the IMEI here so as to not show my actual IMEI

                  AT+CGSN
                  
                  358510000000000
                  
                  OK

                   The command ATI will display info about the module

                  ATI
                  
                  NEOWAY
                  M590
                  REVISION 01.30b
                  
                  OK

                  This thing wouldn't register the SIM on the network and upon further reading .. GAME OVER!

                  I live in USA and no carrier supports the 900MHz and 1800MHz frequencies that this module operates at! :)

                  Look at this map and you can see that you can use these modules in pretty much the WHOLE WORLD except for North America and most of South America :(
