Unfortunately on 01/11/2020, Telstra will discontinue to provide Premium SMS service to their wholesale service providers.
What is Premium SMS
The Premium SMS feature allows you to access a variety of Premium SMS services from third party content providers. Premium rate short message services (SMS) allow content providers to offer value-added services to mobile phone customers using more memorable numbers. Services include specialist weather information, competition entry, ring-tones and wallpapers. These services have been offered in Australia in the number ranges beginning with 19. Examples of these types include: Sunrise Cash Cow
Why is Telstra Wholesale Exiting Premium SMS?
Premium SMS service numbers and usage have been in rapid decline with customers using other internet based services as alternatives. The infrastructure used to support Premium SMS for Telstra Wholesale customers is ageing and does not justify further investment.
