The activation process worked for me back in January 2015. My cell # with Wind has remained activated in iMessage and FaceTime since then (through the update to iOS8 and then iOS9).
But then something went wrong with my iPhone 6 (unrelated to iMessage or Facetime) after I updated to iOS9, and Apple recommended that I restore the phone and set it up as a new phone (not restore from backup).
So I need to repeat this manual activation process ... except that I cannot get it to work again.
After trying many times, each time waiting 5+ minutes to pull the log, there is no Hex code from Apple within the log. I've waited as long as an hour to pull the log, but still no Hex code. When it originally worked for me in January, the Hex code showed up in the log within 5 minutes.
BTW, I did log out (deactivate) my AppleID from the following services prior to starting the activation process: iCloud, iTunes & App store, iMessage & FaceTime.
Any suggestions on what is going wrong?
