I do not use data that much except for Whatsapp and that does not use much, so to me it is not that important.
A whole lot. I upload data probably every two days to browse the internet and use all my apps and it is very costly.
Believe it or not, I use a gig every week which really hurts my pocket. I use the internet for study purposes and it is so expensive.
I try to limit my time on the internet or on apps so that when I do buy data, it lasts because it is so expensive these days and it looks like prices increase every month.
I used to upload data but it would disappear. These networks are making money off us, so now I do not buy data at all.
