On mobile, I probably use less than 500MB because with Telkom Mobile FreeMe, you get 500MB free for WhatsApp and these two bundles only get used when I'm not at home or work because there I'm connected to the work or home Wifi.
200-300GB a month on average. 20mb Fibre.
500GB last month.
I dont really track usage as I'm uncapped. I only check it out of interest every now and then.
I used to stream series/youtube in 720p. Now that I'm uncapped, I enjoy the full 1080p experience.
