Twilio permission to send sms has not been enabled for the region indicated

I'm a new Twilio user and am trying to test sending an SMS using my Live credentials, purchased From number, and valid To number. I'm receiving this error: Unable to create record: Permission to send an SMS has not been enabled for the region indicated by the 'To' number

AFAIK, sending IS enabled for the United States. Is there something else that I'm missing?

Thank you.

What you need to do is go to your Twilio console, to the Geographic permissions for SMS section and ensure you have the permission checked for sending to the US.

You can enable the region by checking the regions in Twilio Settings Twilio SMS Permission Settings

As I m facing the same issue "Permission to send an SMS has not been enabled for the region indicated by the 'To\ number", then I enabled all the regions and it worked perfectly

You need to enable Geographic permission for the region were you want to send the sms to. You can do that here https://www.twilio.com/console/sms/settings/geo-permissions

If you are using it for registration process consider using their "verify" service which allows international phone numbers instead of the "programmable sms". Otherwise you have to manually enable the countries.
