Whatsapp on an S3 WIFI tablet

Hi,

I know there a 6 million questions on the net about this but I cannot find one that has the elements I need.

I would like to install whatsapp on a Samsung 3 10" tablet. I do not have a 3G card, (but its is a 3G tablet so the slot exists), so its needs to be a wifi only version. I do not have a smartphone - only a classic mobile from the 1990s.

Is it possible to have Whatsapp in these conditions?
If so how do can i go about installing it?

Thanks for your help!
