As far as I know WeChat is popular in some arab countries too - I use WeChat to communicate with a chinese friend, but the users that show up nearby me are mostly Arabs.
Messi was in a few WeChat commercials, so maybe in South America this could be a useful tool too.
Maybe someone with a more profound insight can share on this.
