Symeon, I can confirm that you can't tell if a US number is a mobile. I have another business where I use Pick as the backbone, and we provide phone numbers, short code, bidirectional text/SMS (broadcast outbound and process inbound requests), and related services internationally - and it's all done with BASIC. In short, anyone can port a land line number to a mobile, and transfer mobile numbers amongst carriers to a point where you never really know anymore. This is a good thing in a way, it's the same sort of "federation" that we enjoy when we don't have to know the OS under a website, or the mail server under an email address. My suggestion would be not to try to be so smart. Just ask the user if they want to provide a mobile number And if they want to opt-in to SMS messages. You don't want to be one of those slimeballs that send text messages without approval, and in some areas that might be illegal anyway.
