Emoji icons are picture characters that are very popular in Japan for text messaging. Nearly all mobile phones in Japan have Emoji icons built-in. Since the release of firmware 2.2 in late 2008, Apple has brought Emoji icons to iPhone. However, it is for iPhone users using Softbank network in Japan only. For those who want to use Emoji icons on iPhone, simply follow the step-by-step procedures:

Step 1: Launch App Store and search for "Emoji Free". Simply install it and its free apps.

Step 2: Once installation is done, launch it and click the “ok, lets do this!” button to proceed.

Step 3: The process only takes a few seconds. After that, your iPhone is allowed to use Emoji icon.

Step 4: Click HOME button to go back to home screen. Tap “Settings” -> “General” -> “Keyboard” -> “International Keyboards” -> “Add New Keyboard…”. Tap on “Emoji”.

Step 5: You should notice a new Emoji keyboard installed after it goes back to the previous screen. You can then launch any iPhone app to try out the feature. To switch between different keyboards, you can tap on the “globe” button. In case it doesn’t work, restart your iPhone and try again.
