I am using whatsapp from last 5 years I got that this is the best app ever when I started using whatsapp they ask for 1year free subscription but after that they make it free for life time . this software is very easy to use I am chatting with my friends sharing my views and after updates I am sharing pictures and long videos also I making groups.
My friends adding me in groups I can chat privately as well as in groups also I can share my memories in groups and with my friends another thing that I like the message will deliver in less than a minute I don't think that sms service is fast than this . there is no limit of messages pics and use very low data I think this is a very cheap service ever. every thing ks very fine easy to use and easily anyone can understand
