Have just been using those Tronix tutorials to other week, very all good, but note his paragraph about using it with the Mega board, though expect there is a work around somewhere to be found.

If you shield is different, you’ll need to change the TX and RX pin numbers. This also means you can’t use an Arduino Leonardo or Mega (easily). Finally – note this for later – if your shield is having problems sending data back to your Arduino you may need to edit the SoftwareSerial library – read this for more information.
