title: What is best hardware solution for sending sms?
body: <p>I have a task to create production system for sending sms, for approximetly 10 000- 20 000 in a day. Our company have an agreement with local  provider, and have multiple SIM card. I'm looking for 3g modems or some hardware (like GoIP) but i need very stable and quick solution. 
  What could you advise? 
  GoIP is cool, but isn't stable enough. </p>
