Q: iOS 7 iMessage won't activate

I too bit the bullet and did a complete backup and restore in iTunes, and it took care of the issue, so if all else fails or if you just want to fix the issue right away, it looks like a restore is the way to go

I screamed cause I love apple but I use FaceTime and iMessage and I am so sad cause apple was good. They need to step up their game cause I will call apple to complain I literally tried 100 times I even restarted my iPod touch 5. Anyone agree

Same issue facing with my iphone 4S.. Any solution?????

The only thing that worked for me was to restore my phone. Back up your phone to iCloud or your computer. Click on settings>general>reset>erase all settings and content. After your phone resets it's self follow instructions. Put in your Apple ID and password. When your phone is back up go to settings>messages and make sure iMessages and SMS are turned in. It might take a couple mins for iMessages to "activate". It's the only thing that worked for me yes it takes sometime to download all your apps and music again but it works. You might want to connect your phone to iTunes after and make sure your music downloads.

i have tried each and every1 of these so scalled solutions and not one has worked for me, seems like appl have yet agen dropped a ball, need to pull there heads out the sand......

Just on the offchance - check the sim if its new.he phone worked but

My partners is the same can someone tell me what to do please I'm going to oz and need to be able to FaceTime him

I tried the restore and airplane mode and all that stuff...didn't work.  Only thing that worked for me was the deactivation and reactivation per Kari on You TUbe.  see previous post... I haven't even upgraded to 7.0.2

because I'm concerned it will happen again.
