SMS Sender ID Changes & Regulatory Alignment

Upcoming changes to SMS Sender IDs for Telstra Wholesale and Octane mobile services will take effect from 9 June through to 1 July, with all notifications transitioning to the sender ID “MOBILESVCS.”

These updates align with new ACMA regulations requiring registered and verified SMS sender IDs from July 2026 to help prevent impersonation scams and improve trust in business messaging. Customers and partners should review the upcoming changes and prepare for the transition to ensure continued message delivery and compliance.

GST Removed from Late Payment Fees

Following a review of ATO guidance, we identified that late payment fees should not have GST applied to them. Where a late payment fee is characterised as a penalty for late payment or compensation for a delay in receiving payment, it is not considered part of a taxable supply and GST does not apply.

As a result, we have permanently removed GST from late payment fees, effective immediately and applicable to all future billing statements.

What This Means for Your Fees

If your late payment fee was previously configured as $13.64 (ex GST), the total charged to customers would have been $15.00 including GST. Going forward, customers will be charged $13.64, with no GST applied.

If you intend your customers to continue to be charged $15.00, you will need to update your late payment fee to $15.00 in Octane.

Action Required

Please log in to Octane and review your late payment fee settings. If your current fee does not align with the amount you intend to charge, please update it accordingly.

Please note that the Collections UI currently displays “Ex GST” next to the fee field. We’re in the process of updating this label to avoid confusion. In the meantime, please be aware that any late payment fees configured in Octane will be charged as entered, with no GST added.

• Octane Enhancements: New features are now live, including improved usage reporting, streamlined plan creation, and a more efficient activation and porting experience.

• Roaming Fraud Protection: Automated fraud detection is now in place for international roaming, with safeguards to block suspicious high-risk calls while maintaining other services.

3GB Pooling Plan Refresh – Final Reminder

We are introducing an important update to the QueryBalance, QueryBalanceV3, and QueryService APIs, effective the evening of Wednesday, 11 March 2026.

What’s Changing

These APIs will now validate whether a service is active on our platform before making a downstream API call. Specifically, they will check that the provided service number does not have a recorded disconnection or release date.

If the service is inactive, the API will return:

"Service is inactive"

Previously, requests for inactive services were passed through without validation.

What This Means for You

If your integration queries service numbers that may be inactive, you will need to ensure your application can handle the new "Service is inactive" response appropriately.

No changes are required if you only query active services. However, we recommend reviewing your existing error and response handling to ensure compatibility with this update.

Why This Change Is Being Made

This enhancement improves platform stability and performance by preventing unnecessary downstream requests for inactive services. Reducing avoidable traffic helps protect overall system reliability and ensures consistent performance for all customers.

Testing & Support

This new behaviour is already available in our test environment. We strongly recommend validating your integration prior to the 11 March 2026 release date.

Please take a moment to read through the details here and help ensure smooth implementation.
