I think it is a proposal, being experimented by Vodafone and Deutsche Telekom (possibly others) in Germany only: https://www.wired.co.uk/article/trustpid-digital-token-supercookie https://www.wired.co.uk/article/trustpid-digital-token-super... and recently they were joined by Telefonica (Spain) and Orange (France): https://www.digitaltveurope.com/2023/02/13/deutsche-telekom-ag-orange-sa-telefonica-sa-and-vodafone-group-plc-team-up-to-create-a-joint-venture/ https://www.digitaltveurope.com/2023/02/13/deutsche-telekom-... tests there are still to be carried from what I understand, the EU approved the joint venture, but nothing about the actual protocol/method. It is also not clear (to me at least) if it is related to mobile operators only. I would expect that - in due time - the one or the other EU country regulators will accidentally wake up from their eternal sleep and notice it.
