Text Enablement for Toll-Free Numbers (US) - Sinch Letter of Authorization

Text enabling your existing toll-free telephone number allows you to keep your number with your current carrier, while adding SMS service capabilities to that number via Sinch. When you text-enable your toll-free number with Sinch, your toll-free number will not be ported to Sinch, your voice service will stay with your current carrier.

To text-enable your toll-free number, you will need to complete a Letter of Authorization in the Sinch Build Dashboard. Follow the steps here to get started: Hosted Messaging for US and Canada Numbers.

Contact Sinch if you have any questions.
