Every chat app I've used (pretty long list because different countries have different preferences) works fine, regardless of how you connect to the internet. In other words, even though your WhatsApp account is affiliated with a specific phone number (registration requirement), you can use it independent of that number (e.g. wifi, Ethernet, different mobile provider).
