I have recently arrived in Germany and wanted to buy a phone connection for myself. But I observed due to the Coronavirus all local shops are closed. So I tried to order a simcard online. Currently I do not have my own post box as I am living with a temporary landlord. She told me to forward all my mails and packages to her postbox by putting her nameas C/o.
But while ordering a simcard there was no option to add a C/o in the address box.
How do I complete my purchase then?
