not sure I understand this. You can lookup which carrier a user uses based on area code and next three digits? what if user ports their number from one carrier to another?
since twilio is so cheap, it's almost always better than email-to-sms. For example, you don't need to figure out which gateway to send to, and google voice users won't be prevented from getting sms.
