We would like to remind you of an upcoming regulatory change impacting SMS delivery to Australian mobile numbers.

Starting 1 July 2026, at 12:00 AM AEST, the Australian Communication and Media Authority (ACMA) SMS Sender ID regulation will be enforced.

All SMS messages sent to Australian mobile numbers using an unregistered alphanumeric Sender ID will be overwritten to Unverified by Australian telco networks.

To ensure uninterrupted SMS delivery, you much register all Sender IDs used for messages to Australian recipients before 1 July 2026.

If you require help with Sender ID registration or have any questions, please contact our support team at help@sopranodesign.com.
