Mobile internet sites have become more data intensive, so it's not surprising that data usage has increased along side data limit increases.
That's true and I'm sure the data speeds have increased, as well too. But 16.5gbs ten days into my billing cycle is quite ridiculous considering it's regular browsing, maybe 1-3 YouTube videos (8 mins each) per day, and no music streaming. Maybe tinder is using too much data
It used to be 5gbs in ten days last year before they increased their throttle limit.
