Charge still is regulated to 7.7EUR per GB, but that is not its cost. Cost is indeed negligible as data is mostly transferred on exactly the same networks as the rest of Internet traffic in EU and nobody sane argues that you should pay 7 EUR for each GB you transfer.

If I divide my monthly internet bill with the amount of data I transfer during it, then price of GB of data transfer is indeed close to nothing.

To add to that: I can buy wholesale bandwidth within Europe with some ease for <$2 per TB transferred. If you look at quotes for undifferentiated transit from pure bandwidth providers it will be higher, as they typically price based on global routing, but when you know your breakdown is heavily tilted within a region, you can get massive discounts by e.g. limiting 95% or whatever of your capacity between European networks where the provider will exchange most of the traffic via peering - of course the big carriers do their own peering and own their own networks and effectively pay event less.

But even the most price-gouging "captive audience" transit providers (e.g. in data centres without multiple choices of carriers) rarely charge more than ~$10/Mbps (depending on utilisation down to ~$40 per TB transferred or about 0.04 cents per GB...)

Then have the roaming charge regulated to 7€ per terabyte, instead of 7€ per gigabyte as now.

Maybe eventually, but the point is they had to start somewhere, and 7 per GB is still a substantial reduction.

The EU parliament wanted to go much further, starting at 4 and gradually reducing to 1. They'll get pushed further down eventually, but at the same time nobody wants to overdo this and cause problems for these providers by going too fast.

My point is that they should regulate the extractive pricing between operators before they regulate the pricing operators have to give to end customers.

Now those operators that have been competitive will suffer. Those that have been extractive towards their own customers and their competitors will benefit.

That's below the price you pay for data transfer from a server at AWS.. I agree that €7/GB is probably too high, but will still be higher than for internet via cable.

AWS is a notoriously bad example as they're one of the most expensive places you can get bandwidth. I have projects where my entire infrastructure costs less than what the bandwidth charges alone would cost me at AWS...

It is a cost to my operator, and it is a cost the the EU has explicitly approved.

It would be if it was one way only. In practice users from all telcos roam on other networks, negating large bits of this exchange. Real price per user is much lower.

The roaming is far from symmetric.
