I thought you might have deducted the solution yourself after my explanation.
If you want to send out more that 720 messages within a one hour timeframe and you also want it sent out reliably, you need to get access to a real SMSC or a SMS service provider like clickatell or Mobileway. If you want to stay with GSM modems, you can make it more reliable by using the SQLbox. But, you can't make it faster than the maximum bandwidth of the signaling channel of your Mobile service provider.
