It is not possible to use AddaLine numbers with services such as Whatsapp, Facebook etc. Reason being that these companies want you to use your real SIM-card number to validate with them. Hence, they block virtual numbers such as the numbers we provide.
There is nothing we can do to change this. You would need to contact the company in question and request them to allow your AddaLine number specifically and they can usually do so.
