After performing a cost calculation for my condition monitoring cloud platform product portfolio (connected devices sending data to an IoT core) I was shocked at how expensive Telstra's M2M monthly data plan is compared to all other services. Furthermore, it's AUD3.00 a SIM card (below 100 units) or AUD2.50 (above 100 units) and they deliver domestically for a flat rate of AUD15.00.
I am able to run my entire cloud platform (storage, messaging, cyber security services, database queries, notifications) for half the cost of the Telstra product. This is a rip off!
