If you use akp on your phone this might explain it. Sigs especially take up a lot of mobile data to load. Or maybe think of any other website like that.
This thread is wild to me because here I pay <$10 a month for 2Gb data Per DAY and unlimited calling. I usually end up using all of it though every day so that's 60GB per month.
wow! That's such a good price. I have heard that the US (where I am) has higher prices and worse data speeds than most other places.
Oh I should look at the settings to turn off sigs
