How to active iMessage on iPhone?

IMessage can be easily turned on by heading over to settings>message, and frome there you should see an option stated as iMessage. Enable that option. From now on your number would be registered as an iMessage number, so if anyone with another iPhone who has iMessage turned on their device and they messaged you, you would get the messages through iMessage only, not text. Hope this helps

Setting> Messages> Turn iMessage on. You must have an itunes account to use it though.
