Only good thing about telstra internet is the free foxtel rort it beats paying for Kayo and using it's garbage android app.I haven't checked - I was lucky that my Smart TV was smarter than I thought, and I realised I didn't actually need the TTV at all. The Interwebz suggest it may keep working as a media player if you don't connect it to the internet but I think the TV does that as well.
I have Telstra Internet, 2x Telstra phones and 2xTTV. You'd think I'd get some sympathy out of them, but nope. Couldn't care less when I went in to haggle over it. Sod them. I'm sure Aldi mobile is just as good for a third of the price...
