This will not work. A Twilio Number cannot receive messages from a short code. Almost every single two factor authentication code from a bank or other institution comes from a short code. No number you receive or port into Twilio is Classified as a mobile number – so they cannot receive messages from short codes. I spoke to engineers from Twilio at the 2018 Signal conference and they confirmed - there is no technical limitation, but they would have to do a lot of work and deal with a lot of spam issues if they allowed their numbers to be classified as "mobile" and able to receive SMS from shortcodes - and they are declining to do that for now. So whether you source a new number from Twilio or port in an existing mobile number, once it hits Twilio it is no longer a mobile number. Yes, you can receive SMS/MMS from "normal" numbers just fine.
