We had a great email from a customer interested in developing with Telstra's IoT network, who was trying to plan out their expected data costs.
The great news is, Telstra only charges for the payloads our customers send or receive. Any packet additions made by Telstra to safely and securely transport customer data through our network are not included in our usage charges. For example, if your payload is 35kb, the data charge to your account will be 35kb.
If you are planning to launch a large scale LPWAN IoT deployment, and have any questions or concerns, let us know!
We also ask that all developments with our network comply with the Wireless Application Developers Guidelines for IoT and Our Customer Terms which can be found online here https://www.telstra.com.au/content/dam/tcom/personal/consumer-advice/pdf/business-b/dataservices-m2m.pdf
