Hi,
I bought the Arduino GSM Shield 2 and I am trying to send an SMS.

I am using:
 - Arduino Mega ( I did the necessary changes for Mega)
 - standard GSM library ( 1.0.6)
 - sim card (in Austria) which has been checked with a phone

What the program does:
  -  connect to gsm  and turn on a led when connected ( this part is working)
  -  send an SMS when I push a button ( this  part does not work)

The code is pretty close to the samples provided by arduino web site.

 
#include <GSM.h>
#define PINNUMBER "XXXX"

const int buttonPin = 4;     
const int ledPin =  12;     
const int ledPinBoard =  13;   

int buttonState = 0;     

GSM gsmAccess(true);
GSM_SMS sms;
boolean notConnected = true;
boolean doSend = false;
char remoteNumber[20]= "XXXXXXXXXX";

void setup() {
  Serial.begin(9600); 
  pinMode(ledPin, OUTPUT);
  pinMode(ledPinBoard, OUTPUT);
  pinMode(buttonPin, INPUT);
  digitalWrite(ledPinBoard, LOW);
}

void loop() {

  buttonState = digitalRead(buttonPin);

  if (buttonState == HIGH) {
      doSend = true;
  }

  if(notConnected)
  {
    if(gsmAccess.begin(PINNUMBER)==GSM_READY) {
      notConnected = false;
      Serial.println("Connected");
      digitalWrite(ledPin, HIGH);
    } else {
      digitalWrite(ledPin, LOW);
    }
  } else {
    digitalWrite(ledPin, HIGH);
  }

  if (doSend) {
    doSend=false;
    sendSMS();   
  }

  delay(1000);
}

void sendSMS(){

  char txtMsg[200]="Test";

  sms.beginSMS(remoteNumber);
  sms.print(txtMsg);
  sms.endSMS();

}


Th Error which I get after sms.endSMS(); is :

AT+CMGS="XXXXXXXXXX"%13%
58 62>%13%%10%>
Test%26%%13%
58 81>%13%%10%> %13%%10%+CMS ERROR: 159%13%%10%


Error 159 means "Unspecified TP-DCS error" but that is pretty much all that I found about it ( the name).
Am I missing something ?
Is there maybe a workaround for it ?

Thanks !

Update:
Using another SIM from another GSM provider solved the problem.(no code or hardware changes).
