- Scenario

- Observed behavior
- Businesses must navigate Adobe Sign's tiered plans to find out which versions support SMS authentication and how to configure it correctly for regional usage.

Upgrade to a Business or Enterprise Adobe Sign Plan
SMS authentication is an advanced feature that requires upgrading from an individual account to a higher-tier organizational plan.
Individual Adobe Sign plans often lack advanced multi-factor authentication features like SMS and voice verification. To use phone authentication for clients in Australia, you will likely need a Teams, Business, or Enterprise agreement.
Log in to the Adobe Acrobat Sign portal, navigate to your Account Settings, and review your current active plan.
Reach out to Adobe Sales to confirm the availability, licensing, and transaction limits for SMS authentication specifically in the Australian region.
Upgrade your subscription to a Business or Enterprise tier that explicitly supports phone authentication workflows.

Configure SMS Authentication During Document Send
Once you have the required plan, you can explicitly enforce SMS verification when preparing a document for client signature.
