I was on naked ADSL for a while a year-or-so a go. Then my ISP offered to transfer me to a better-priced deal with a bundled POTS. Who's plan were they on-selling to give me this? Optus'.
The article's deal doesn't sound bad, but I am presently paying $70 per month for much the same thing (more mobile credit than I use, a similarly effectively-free landline) but 200GiB quota down and un-metered up. Which ISP? Well, technically Optus, who's plan my actual ISP is on-selling to me in this case.
