Dann hattest du wohl Glück. Mir wurde jetzt das geantwortet:
Fairphone doesn't provide a substitute phone service. After carefully evaluating this possibility, it appeared that this service would be unsustainable on a logistic, environmental and on an administrative level. As a small social enterprise, we currently do not have the resources to provide this kind of service. Some network providers offer it, so I suggest you check with yours if they could do something to help you.
