Good questions. Ideally the website would make this clearer upfront.

Our upstream provider of virtual numbers filters out verification codes from services like Google, Facebook, and Twitter.

The advantage of using a physical number is that no messages are filtered out.

They are more expensive because they are more expensive to me. And the typical customer only uses a physical number for one day, where the minimum purchase time for a virtual number is one month, so the effective price to the customer is "only" 4 times as much.

It's better than Twilio because Twilio filter out verification code messages, and because Twilio don't allow anonymous signup or Bitcoin payment.

Is Twilio your upstream provider?
