Hike messenger! yes this is the most used messenger after whatsapp. It has some pretty cool features like calling, messaging, rewards earning, free message to direct number etc.
It also provides very cool stickers to make your chat conversation more interesting. I just love its whole collection of stickers. So I am definately giving it four stars for all of its features. And definately recommend others to install and try it atleast once. You’ll start loving it day by day.
