Sending sms problem.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I download the gsm-shield files
2. Add the library
3. I put in my sim card.
4. Add external 9v battery.
3. I go on to try GSM_GPRSLibrary_SMS example.

What is the expected output? What do you see instead?

I had expected to see a message send to the phone number written 
in the code. The output says message sent but the phone does not
recieve it.

What version of the product are you using? On what operating system?

I believe its the second version here is the module link from
ebay:

Hi

I am using arduino uno and the sample does not work even after I set all the 
right configurations. Message print on arduino says sent but I recieve nothing!

how does your rfid communicate with your board serial rx and tx ? There
might be conflict between your shield and rfid check software serial code. 

Maybe.

Pin 10 is connected with TX of RFID module
Pin 11 is connected wit TX pin of GSM module
Pin 12 is connected wit RX pin of GSM module

As far as i think, there is no conflict

Hi

The gsm shield uses software serial so regardless of the connected pins in the 
software
serial code they should be no conflict! So if in gsm software serial is pin 2 
for rx and another tx. rfid should not conflict on software serial bases.

Thanks.
