Interestingly I was looking at this plan and there's another deal of unlimited data popped up at OZB.
$35/Month Unlimited Mobile Plan (up to 20Mbps) @ Felix Link, also on Vodafone network, but on 4G/3G.
So the difference is the max speed 50GB (5G enabled) each month, (or 60GB/$40 or 100GB/$45)
After that, you'd be better off on the Felix plan 20Mbps where this Vodafone one is capped on 2Mbps.
Choose your needs.
Also Cashrewards has 65% on month to month sim only Vodafone plans at the moment.
Too late. Already posted
