6S Plus will not activate iMessage. Missing 90% of my messages. 9.1 beta 2.

Had the same problem yesterday. Took almost 12 hours to get it working.

Tried dozens of things - then it got activated, stopped again, activated, stopped .. and so on.
Suddenly *poof* working.

Same issue for me. I downgraded to 9.01 and still having this issue. FML.

Hi Josh,


Towards getting this bug fixed, it would be good to report it via either the Feedback Assistant app or with https://bugreport.apple.com.


In the meantime, a workaround that has fixed many such issues for people on 9.1b1 & 2 is to make a new iTunes backup and then reset to "factory condition" (as Apple put it) with Settings > General > Reset > Erase all Content and Settings, and after that restoring from the iTunes backup.


Let me know how it goes,
