It's a free app. Search it in the app store and download it. It will give you quick instructions on changing a few settings once it's dl'd, then you're good to go.

You should try to press the circle thingy on your keyboard keep pressing it till you find the emojis

First you need to get the app which is free then after its loaded to onto your setting in your phone go onto general and then go onto keyboard after you have clicked on that go down to the bar that says keyboards and open it up there you click add new keyboard and scroll down the list till you find emoji click on emoji and it will be added to your keyboard to use it when you are typing click on the circle at the bottom with the lines through and keep clicking until you get to emoji
