I wonder how they factor unlimited plans into this? In Chile, the mobile internet is quite cheap (and usually plenty fast, LTE is widespread and download speeds > 10 Mbps are common) per GB but unlimited plans are also common. E.g., I pay something like $1.50 a week for unlimited internet and calls, and since I can use 60 GB a month easy, that works out to ~10 cents a GB, considerably cheaper than what the chart shows for Chile. It's also about 100x cheaper than the $10/GB ballpark I paid in Canada. Yeah, one hundred times cheaper.
