How to turn on imessage for iPhone 4?

So I asked this same question before but I forgot to include that I had a Verizon phone that I had bought from a friend and he took of the service. So I don't know if that's the reason why It won't activate but if it is then what do I do?

What iOS are you running? Do you have an apple ID? Is it just that you don't know how or is there a problem with the phone? Have you had iMessages before? We need more information before we can specify the steps needed to activate iMessages.

I'm sure someone will help you if you specify!
