Cost of 1 minute of 5G transfer on the iPhone 12 in different countries

That pricing comparison makes no sense.

For example in Finland from one carrier, unlimited data:

5G 300 Mb/s 29.90 EUR/month (cheapest 5G option)

5G 1 Gb/s is 44.90 EUR/month (currently the fastest option)

In other words, you pay for bandwidth, not data. Unlimited data means unlimited data. https://twitter.com/mikko/status/1315178802356649986 ,discussion https://news.ycombinator.com/item?id=24749971
