title: Twilio vs google voice api for SMS
body: <p>I am building a mobile app (android et al) that I need to use SMS for. The SMS would simply send an activation code when user first registers with my app (and maybe one other equally simple usage). Since Google is a respected company and Google voice is free (<a href="http://code.google.com/p/google-voice-java/" rel="noreferrer">API</a>), I was thinking of going with Google Voice. However, a lot of developers seem to be using Twilio. Is there an advantage to using Twilio SMS over Google Voice SMS for my basic usage of sending verification code (again, Google Voice is free)?</p>
