WhatsApp had a blip of popularity in the US back in 2013, but people moved over to iMessage, Facebook Messenger, and Snapchat in the years since. I mostly blame the design, since WhatsApp was quite hard to look at for years. I get the feeling that people in the US view WhatsApp as old technology. I still use WhatsApp occasionally to talk to friends from European countries, and especially if I'm on vacation somewhere in Europe. But then again, the same goes with WeChat and China. The feature set in all the messaging apps are comparable. You have to remember how large the market penetration is for iPhones in the US, so the default is iMessage (which falls back to SMS).
