Free WhatsApp: No Subscription charges even after first year of usage

Now owned by Facebook company, WhatsApp gets completely free without subscription charges for all users even after using it for 1 year.

Previously WhatsApp charged $1 annually, after giving its users free service for the first year of their usage.
In a blog the company said, that this announcement definitely does not mean that they will allow the third party advertisements to compensate money. The company instead plans to introduce tools that allow users to communicate with organizations.
