Tech question: Can tablet replace smartphone?

[netzerkaiser]

Hi guys, I don't like smartphones. Does anyone know if having simple text / call mobile & a tablet cover all issues? I've joined a few sports clubs & they arrange impromptu meet-ups via WhatsApp. Can WhatsApp be installed on tablet without having smart phone? Any advice would be most appreciated. To summarise, I don't like smart phones, my deteriorating eyesight is a key reason, but I will need WhatsApp.
