I’m not in favour of any of the age restriction stuff UK government is doing.

Good argument, but:

Phones in the UK can be bought without a contract and untied to any network.

Pay as you go SIM cards can be bought without a contract.

Credit cards used to make purchases online require users to be 18 or over. Debit cards on the other hand can be issued to those under 18 (but a bank account will require evidence of ID, address, age). https://www.gohenry.com/uk/blog/financial-education/what-age-can-you-get-a-debit-card-in-the-uk
