Small as for this not buying , not that other methods need to be pasued , of course what's going big already should continue whiles this is added too.
Of course its just one day, but I and a lot of people practice this everyday trying to buy as less as possible and reaching self-sufficiency.
Why do we need a Sim and number , its just a way for government to keep control and manipulate.
Time to promote a simless future.✊
