Apple will soon release iOS 12.1.2, the fourth update to the iOS 12 operating system since its September launch. iOS 12.1.2 comes just two weeks after the release of iOS 12.1.1, and one week after Apple seeded the first iOS 12.1.2 beta to developers.
The iOS 12.1.2 update will be available on all eligible devices over-the-air in the Settings app. To access the update, go to Settings > General > Software Update. As with all iOS updates, iOS 12.1.2 is free to download.
According to Apple’s release notes, iOS 12.1.2 is a bug fix update that focuses on addressing issues with eSIM activation and a cellular connectivity issue in Turkey. From Apple’s release notes:
iOS 12.1.2 includes bug fixes for your iPhone. This update:
– Fixes bugs with eSIM activation for iPhone XR, iPhone XS, and iPhone XS Max
– Addresses an issue that could affect cellular connectivity in Turkey for iPhone XR, iPhone XS, and iPhone XS Max
The timing of the iOS 12.1.2 release is curious as Apple often seeds more than one beta before launching a software update. It’s likely that iOS 12.1.2 is addressing a bug that Apple did not want to wait to fix.
eSIM functionality was first introduced in the iOS 12.1 update and expanded with iOS 12.1.1. In the U.S., T-Mobile, Verizon, and AT&T are all now supporting the eSIM feature, as are multiple other carriers around the world.
