I keep getting an annoying REG90 unable to connect error message.

My Nokia Lumia 925 was just upgraded to WP 8.1 and now every few seconds I get a cryptic "REG90 Unable to Connect error message. It's driving me nuts! How can I shut it off? Any ideas what this message means, and if or when it will ever be fixed?

I had this problem shortly after the Cyan update. I called TMO tech support and they texted me some patch. That didn't work, so they told me to go to a TMO store to have my SIM card checked.

The store rep said that my SIM card was not configured for WIFI calling so they replaced it with a new one. It works fine now.

Your problem is most likely an old or defective SIM card. Or, you don't have a 911 address configured in your TMobile account, which you can do online.

Good luck.
