I'm using dodo Internet for almost a year in SA and had no problems.
My brother and sisters in syd are also using dodo. They use it for more than four years on torrent and no issues.
Dodo is just a reseller they use other ISP's infrastructure.
For example in my previous address, dodo is using Optus. I'm paying $60 but I get unlimited Internet using optus infra.
In my new address, dodo is using Adam Internet infra. Adam Internet has no unlimited plan so to pay $60/month is a good deal.
How did I know? In my previous address, optus website is what I saw when I was waiting for dodo to activate the connection. In my new address, Adam Internet is the temp website.
I don't want other providers espeially Teltra, their very strict especially in downloading torrents.
Hope this helps.
