Yeah their credits are a bit sneaky :) Twilio only supports US numbers which is a problem. If you're looking at telephony companies, Tropo (https://www.tropo.com/) is only 2c per message and sorta supports international numbers. Their 'support' is basically "if it works, awesome, if it doesn't, well we never said it definitely would". It's worked well to Australia for me so far. International support is coming at some point, though I don't know if it will still be at 2c per message.
