I am using whatsapp since 4 years. I really like this network. this network has very easy to use and most secure. all our personal data and information is strongly secured and well protected.
The design and usability of whatsapp is very nice. most of whatsapp users use their APP on the phone. there are less people use this network on PC/Lap Taps when compared to mobile users. the load time of this app/website is very less.
The service and support given by whatsapp are awesome. we can store so much of our data in their storage location. it is absolutely free for cost to use. it is only requires a net connectivity. whatsapp available for all OS. it has different APP for different OS.
we can share/send photos, videos, logos.etc through this APP very easily. the content timeline less is very nice. it consumes very low memory space in our phone/pc. it also provides web calling specialty to all their users.
so I strongly recommended this social network for people who are willing to connect to other people.
