Emoticons are a well-hidden feature of the iPhone that enhances SMS and iMessages and can be used in almost any application that involves typing. Helping you to convey emotions more effectively, emoticons are one of the features of the iPhone that are not known to all users. The iPhone has a whole keyboard full of emoticons in fact, but you need to activate it before you can use it. Find out below how to add emoticons on iPhone. 
A Brief Guide to Adding Emoticons

How to Add Emoticons on iPhone with Apps
There are various apps in the App Store like Emoji Unlimited and Emoji 2 Emoticons that can add other emoticons on the iPhone, apart from the default ones. Having too many emoticons can be confusing though, so it’s better if you keep things simple. Use the default emoticons, which are already present on your device and can be activated with ease, and consider installing additional emoticons only if you get bored of the default ones. That’s not likely to happen anytime soon.
