yeah, I sometimes do the same, but I do call a lot of non US numbers, so I use WhatsApp.
Also at my last Job I flew charter mostly out of the country and WhatsApp is about the only reliable way of communicating with the many contacts you have to stay in touch with... they just won't answer the phone and will rather communicate with you thru your FO or your FA if they have WhatsApp and you don't.
