IOS 7 can't get my imessage to work?

Ok so i have the io7 beta and i put it on my iphone 4 not turned on(carrier not activated ), no sim card, so i use it like an iPod but have apps for free phone with Wi-Fi etc. You get the point lol
so i managed to get the ios7 on my phone and everything Works but my imessage and when i got to my imessage settings it won't slide to the right to turn on and when it does it asks for my old imessage account that i haven't used in a while or it just crashes. I have tried the "turn off Wi-Fi location services etc, then turn them back on "

is this because my phone is not activated by a carrier or?

This problem may have occurred because it is a beta version. Apple my be aware of this problem (if it is legal) there's nothing you can do unless you go back to ios 6.3
