DSL number : L836816 Speed: 2 Mbps/512 Kbps
Total usage : 273.5 GB Free usage volume : Unlimited GB
so i think 300gb package will be great for us heavy users
but keep in mind that you calculations will not be the same with upgraded speed, personally, my consumption is ~ 150 GB every month on 2 Mbps connection, but my line can handle up to 16 Mbps, so if i can stick with 200 GB/month, it will be a miracle.
when you're giving speed to non-geeks people in your house, they will milk every MB by watching videos.
