SMS

Add number to SMS registration

Attaches this number to your existing approved 10DLC campaign instead of running a fresh registration: the number inherits the campaign's approval (no new brand or campaign, no extra carrier fee). Enable SMS on the number first (POST /v1/phone-numbers/{id}/sms; its response tells you whether a reusable registration exists).

POST
/v1/phone-numbers/{id}/sms/reuse-registration

Authorization

Disable SMS on a number

Turns off SMS for the number (deactivates its SMS account). The carrier registration is untouched, so re-enabling later reactivates it, with no re-registration.
