Problem description

I am trying to enable the Dynamic Alphanumeric Sender ID feature in Azure Communication Services, but the option is not available in the portal, despite documentation indicating support. The same problem persists across multiple tenants, with billing addresses always in Germany.

Environment

Azure Communication Services Dynamic SMS/alphanumeric sender ID capability, Standard subscription, affected in multiple tenants, location not specified in case information.

What I've already tried

I reviewed the documentation expecting the feature to be available. The support thread and case history contain no additional troubleshooting steps or configuration changes. I verified that prerequisites are met, including billing profile country, SMS enablement, and regional policies, but the feature remains unavailable.

Current status

The feature is still unavailable despite meeting documented prerequisites. I seek assistance to understand the cause and steps to enable Dynamic Alphanumeric Sender ID in my environment.
