In my country SMS has absurd prices, when Whatsapp showed up it was viewed as a huge blessing, no more having to pay at the time around 1 USD to send 1 message.

In my country SMS has absurd prices, when Whatsapp showed up it was viewed as a huge blessing, no more having to pay at the time around 1 USD to send 1 message... (and if you had 141 characters? well, that is 2 USD now!) Everyone here uses it now, and this include sevearl business and organizations, I heard even some government communication can only be done with Whatsapp, so basically we are stuck with it.
