WhatsApp isn't installed by default AFAIK, but it is one of the first apps installed by millions, if not billions, on their phones.

In Korea, Taiwan and Japan, LINE became the de facto IM. In China, WeChat. But ain't sure if these are usually/always preinstalled in those markets.

Cheers.

In Korea I think the de facto IM is Kakao, LINE is only third (after FB messager) [0][1].
