T-Mobile is performing planned maintenance on their Wholesale file transfer system during this window. As a result, delivery of Call Detail Records (CDRs) will be delayed until the maintenance completes.

Impact:

- Delayed delivery of CDR and usage data

- Files will be delivered once T-Mobile's system is back online

No impact to live services. Provisioning, voice, messaging, and all API operations continue to function normally throughout the maintenance window.

No action required from partners. Reporting data will catch up automatically once T-Mobile completes the maintenance.
