Can I take out insurance without already knowing my date of arrival?

I do not know the exact date of my arrival, yet, can I still purchase insurance?

If you do not know your exact date of arrival, yet, you can purchase the insurance by entering an expected date of entry. In this case, you will receive an insurance certificate with the expected date of arrival. Please inform us about your exact date of arrival as soon as you know it. You will then receive all documents. Before the expected date of arrival, an email is sufficient. If you inform us after the expected date of arrival, please send us some proof of arrival (e.g. a copy of your passport or a plane ticket).
