In that case you'd need an app on your Android phone to relay SMSes between the phone network and your web app. The advantage of doing it via the carrier is that the phone is taken out of the loop and you're directly sending to the carrier via the internet.

I'm fine with that.

The disadvantage of doing that is you than need to stay with that carrier. I'd rather be able to change if my carrier starts doing things that are shifty without needing to change the way I interact with my phone.
