We can save our planet if there is a secret option to switch off sending SIM card to new members.
As new students or travellers do not know how to top up, I help them activate their giffgaff SIM cards by using my debit card. Therefore, I receive a lot of free SIM cards regularly. The worst thing is that I have to put them in the bin as I have nothing to do with it.
Add an option for us SR to stop the free SIM card auto-sending service please, so that giffgaff can save some money and I can save my mail box.
