//for RAM saving.
//If your sketch reboots itself proprably you have finished,
//your memory available.
//If you want to use the Arduino functions to manage SMS, uncomment the lines below.

//Simple sketch to send and receive SMS.
Serial.println(“GSM Shield testing.”);
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
//Enable this two lines if you want to send an SMS.
if (sms.SendSMS(“91********”, “Arduino SMS”))
Serial.println("\nSMS sent OK");
//Read if there are messages on SIM card and print them.
if(gsm.readSMS(smsbuffer, 160, n, 20))
