SMS Not transferring to phone

I'm set up and approved for the SMS. I have my SMS number to transfer to my phone, however, I'm not getting ANY notifications outside of an email, that I have a message. I'm not sure what I'm doing wrong. I seems like I have everything set up correctly. VRBO is the worst! I don't always check my email.. so I have to end up giving out my personal phone number just to be able to communicate in a timely manner. Any help would be greatly appreciated. 

Thanks!
