Needed a cheap churn before heading back to Boost, and found Dodo had a nice deal currently (looks like it might end today - Just says you need to order by 02/07/24, not activate).
You can order the sim card without payment, so order now, think later.
Dodo uses the Optus 4G network.
I have found Boost / Telstra quite average of late. Vodafone on the other hand out performs Telstra on the South East Queensland, Now the new deal with Optus and Vodafone signal is much better if not stronger. I have Telstra Retail and Vodafone Dual esim and Vodafone is always got better signal. Food for thought
