Setting up SMS sending

Send and receive SMS through your number and provider.

SMS runs through OneSimple Phone numbers and your configured SMS provider. The app supports both outbound and inbound SMS, plus delivery status tracking.

Inbound & status

Incoming texts and delivery updates arrive via provider webhooks and show up on the contact's thread and in your metrics.

US 10DLC

US business SMS requires 10DLC registration before production traffic flows. Test sends work beforehand; production sends are gated until your number's campaign is approved.
