Country codes or roaming fees have nothing to do with it. The reason we use Whatsapp is simply to avoid SMS/ MMS (I might have sent one MMS in my life, back in 2008) and network charges for phone calls/ video calls. Basically most of our phone communication activity is over ip, with the only exception of a minority of classic phone calls (as they tend to have better quality).

Lol. Of course it matters: if you do it, by definition someone is doing it.
