Apple has released the fourth update to its latest mobile operating system – iOS 12. iOS 12 was released this September and after that, we have seen iOS 12.0.1, iOS 12.1, and iOS 12.1.1 updates.
With iOS 12, Apple is said to have focused more on bringing stability and performance improvements over the glitchy iOS 11. iOS 12 has been well-received by users for adding a new life to old devices with more speed.
Today, Apple has released iOS 12.1.2 exclusive to iPhones only. This update is aimed at fixing e-SIM activation issues with iPhone XR, iPhone XS, and iPhone XS Max. It also addresses an issue that could affect cellular connectivity in Turkey for iPhone XR, iPhone XS, and iPhone XS Max models.
You can update your iPhone to iOS 12.1.2 using Over the Air (OTA) or use the stock iOS file (IPSW file) to completely erase and update your device.
OTA is the easiest way to update your iPhone to the latest iOS versions. Connect it to a power outlet and WiFi, go to Settings > General > Software Update and tap Download and Install. Your device should be updated after a reboot.
Using IPSW file to update your device requires more time and patience. If you don’t already know how to update your compatible iPhone, iPad or iPod touch using an IPSW file, refer to this article.
