Received below email from Optus today, stating they will end $0/m data sharing SIM from early December.
Thank you for being with Optus over the years. Since you joined us, we’ve continued to update and improve our products, particularly as our customers’ needs and technology continue to evolve.
This means we’ll be saying goodbye to our old shared data plans and moving your service(s) to a new plan. Your current shared data plan(s) has no ongoing cost or data inclusion.
Your new plan will cost $5 per month and will now include 5GB of data per service, which will be added to the data sharing pool used by all eligible services that share data on your account.
What does this mean for you?
From about 8th December 2023, we’ll be moving your shared data service(s) to our new 5GB Shared Data plan, with more detail about your new plan in the Critical Information Summary (CIS). The first month of your plan will be free, so you will not be charged the new plan price until your second bill after the change takes effect.
Really doesn't seem the time for Optus to give whatever remaining customers they have a reason to leave. It's only $5 but they seriously need to read the room.
