The data share SIMs, I was told Optus doesn't do the ones with a onetime set up cost so you could have one for a MiFi or tablet and use it off your data pool. Now it seems I need to buy a data separate data only SIM plan with a monthly cost and add it to the pool. One of the reasons I was recommending Optus was for the data share sim with one off cost to add.
Telstra do them but it's $5 pm, cheapest Optus data SIM is now $20 pm with 3gb data ....hmm Optus at $20pm for a data share sim, or Telstra for $5 pm ........... this makes Telstra cheaper ......
Have not had those for several plan generations now - so not available at all.
And yes - Telstra is in the process of removing the data share sims now also on their new plans.
Someone on an old optus plan asked me to find best deal,
Seems now it will be Belong, get a $25 plan for the phone with 5 Gb data, a $10 plan for the tablet ....for $35 per month they have unlimited calls, text, 2 sims, 6 gb total data, and Belong data pool, and accumulate unused data, top ups are $10 for 2GB if needed, and no auto top ups so no bill shock.
Optus I would need $25 sim only with 3 gb data and voice, and $20 for a data sim ....$45 pm, and extra data is $10 per GB auto added, so possible bill shock.
the telstra deal was $39 for 25GB unlimted voice and text and $5 pm for the data share sim.
