Apple iOS 12.1.2 Has a Serious Problem with Cellular connectivity

"Addresses an issue that could affect cellular connectivity in Turkey for iPhone XR, iPhone XS, and iPhone XS Max"

What exactly did apple do here? Kind of suspicious that they made adjustments to the eSIM specifically for Turkey when Erdogan announced he would be banning iPhones because of coup fears [1]. Did they enable Turkey to listen in?

I think I'll skip this no CVE's update.
