Arduino sample code:

#include <SoftwareSerial.h>
//SIM800 TX is connected to Arduino D8
#define SIM800_TX_PIN 8
//SIM800 RX is connected to Arduino D7
#define SIM800_RX_PIN 7
//Create software serial object to communicate with SIM800
SoftwareSerial serialSIM800(SIM800_TX_PIN,SIM800_RX_PIN);
void setup() {
  //Begin serial comunication with Arduino and Arduino IDE (Serial Monitor)
  //Being serial communication witj Arduino and SIM800
  Serial.println("Setup Complete!");
  Serial.println("Sending SMS...");
  //Set SMS format to ASCII
  //Send new SMS command and message number
  //Send SMS content
  //Send Ctrl+Z / ESC to denote SMS message is complete
  Serial.println("SMS Sent!");

SIM800L GSM GPRS microSIM card Core board arduino

SIM800L Module is a small GSM/GPRS Module and ideal for small ideal projects. The module supports quad-band GSM/GPRS network, available for SMS and GPRS message data remote transmission. 
The SIM800L communicates with the microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands. Besides, the board also supports A-GPS technique which is called mobile positioning and gets the position by mobile network. This feature makes it can also be a tracker module.

The SIM800L can work up to 2Amps current at peak. It also has a low power consumption feature that consumes 1mA Current in sleep mode. You need to power the module from 3.7V to 4.2V as per the datasheet. More than that will damage the module. You can use a buck converter to achieve this voltage range.

Micro SIM Card

LED Blinking status:
If the power to the SIM800L is enough, the onboard LED starts blinking. The frequency of the blinking denotes the following:

Every second:  searching for a network.
Every three seconds: connected to a network.
Twice per second: connected through GPRS.
