Hello Guyz,

I have some questions about Twilio:

1) In the Phone number field on the UNA page, where the user enter his phone number to send the verification code to, is it possible to have pre-populate (pre-defined) country code before the phone number (exemple: +1 for USA)? The user will only have to enter the remaining part of his phone number. I have seen it on many websites and Mobile Apps. It's a great spam protection and it prevents unwanted user registration, specially for regional or country specific websites. 

Example: If a site is an Australia-based website (restricted to people, services and products in Australia only) and the phone number field is pre-populated with the Australia country code +61, only phone numbers from Australia can be entered and verified. It is one of the best way to prevent anyone outside of Australia to register.

2) On the Twilio website (pricing), I can see many plans (Programmable Messaging, Notify, Authy, Verify etc). I am kinda confused. What is the right plan to suscribe to in order to make the 2FA feature available on a UNA site? Is it the Authy, Verify or maybe another plan?

3) Can we set up Twilio on UNA and use it for Phone verification upon account registration only and not for the 2FA in every login?

Thanks
