Why can't I download WhatsApp from the Nokia OVI Store?
The Nokia OVI Store was replaced by Opera Mobile Store in the first quarter of 2015. If you are using an S60 device, you can download WhatsApp from there. However, we strongly recommend that you download WhatsApp from our website, where we always have the latest version of WhatsApp.
We will continue supporting Nokia S60 for the foreseeable future. You can check our FAQ page on How to update WhatsApp to learn how to keep WhatsApp on your Nokia S60 up to date.
