WhatsApp is arguably one of the most popular cross-platform messenger apps available out there. Though until now, WhatsApp hasn’t been free on iOS. You had to shell out $0.99 to get it on your iPhone. Well, for a limited time, WhatsApp is free.
Other platforms could use WhatsApp for free, but for some reason iOS users had to pay up. This change will probably make many users download it, and it will boost the users of the service, which isn’t a bad thing. I wonder how the WhatsApp network will handle the additional load, though.
There are many other messengers, like Viber, Kik, Line, and more that are also free. These days, when you’re in range of a Wi-Fi network, you can definitely save money compared to your carrier’s messaging services, since these sort of messengers replace text and voice messaging very efficiently.
