If you need heavy download GB, then this is a pretty decent deal for the latest iPhone XR 64GB.
Personally I'm not a fan of the leasing and paying $99 to swap every 12 months but it might be attractive for some.
If you do the maths breakdown on the $84/mo option, it's $32.80/mo for the plan of 100GB, plus the $1229 handset ($51.20/mo). $84/mo to own it after 24 months is a decent deal with 100GB.
It's not as cheap as getting a cheaper XR handset from an ebay sale and going on a cheaper plan, but this means the cost is spread over 2 years which is preferable to many than a $1200 upfront cost. There's also not many 100GB plans for around that $32 mark.
Vodafone had $71 with 15gb and 2 months free last December, I didn’t sign up and I don’t know why I waited for Optus to somehow has a similar deal
