Without a second beta like most other beta versions, Apple released iOS 12.1.2 to all iPhone users on Monday, Dec. 17. The update comes just one week after the iOS 12.1.2 beta went live, so why did it have such a quick turnaround? The answer likely revolves around eSIM issues on newer iPhone models.
Some users with an iPhone XS, XS Max, and XR have been having issues activating certain eSIM plans from wireless carriers. Since eSIM is such a big deal, given that it’s a brand new feature only available since iOS 12.1 on these newer models, it’s best to knock out any bugs right away when they happen. Plus, new carriers like Verizon Wireless recently added support, so there are more people experience bugs.
The update also fixed a cellular issue that users in Turkey were experiencing. However, one thing absent from this release is security patches. According to Apple, there were no CVEs that needed their attention at this time.
- 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
To install iOS 12.1.2, open your Settings, tap “General,” then select “Software Update.” Follow the instructions on-screen to download and install the software. If you have “Automatic Updates” enabled, the software will update itself overnight.
Beta testers knew this update was not going to be a major one. Apple only included two points in the release notes for the iOS 12.1.2 developer beta, one known issue, and one resolved issue, as seen below. It’s not yet known if the Accessibility issue was fixed in iOS 12.1.2 stable.
Accessibility Known Issues
Some user interface elements are inaccessible to VoiceOver in the “Electrocardiogram (ECG)” and “Irregular Heart Rhythm Notification” sections in Health > Health Data > Heart. (46505168)
