Upload Sketch Program di atas ke dalam Arduino UNO kemudian Hubungkan Arduino Uno dengan Module Neoway dengan wiring sebagai berikut : 
M590  <-->  Arduino
-------------------------------- 
BOOT <--> GND
GND <--> GND 
5V <--> 5V
RXD <--> D3
TXD <--> D2

Pastikan Lampu LED indicator Neoway M590 berkedip tanda Modem GSM/GPRS sudah ON
Buka Serial Monitor pada Arduino IDE,setting Boudrate pada 9600 - Both NL & CR
