First is not always best
European telcos are right to recoup their 4G+ costs.
5G promises of a revolution instead of an evolution will come at a huge cost, if ever, with the need to multiply terrestrial antennaes, and huge fiber interlinking infrastructures. And that's not even taking into account the need for power efficiency increases of smartphones to benefit from speeds & short latencies for more than a few minutes.
In the mean time, there is very little to be gained by a few percentage to 2x download speed over 4G+, at least for the customers. Videos are downloaded fast enough, and no 4K phone screen makes sense.
