Apple released the iOS 12.1.2 firmware update last week to address some connectivity issues faced by older iPhones in a specific region. The update seems to have fixed the problem for users in that region while replicating it for users in other regions where the issue was not present before. However, a temporary fix for iOS 12.1.2 cellular data issue has been identified and it should be enough to hold users over until Apple sends out another update.
Many users have reported after upgrading to iOS 12.1.2 that their devices often experience mobile data connections being cut. This has left many devices unable to send and receive phone calls as well as text messages. Some users have also claimed that they have been unable to connect to a Wi-Fi network on the affected device.
A temporary fix for the iOS 12.1.2 cellular data issue identified by 9to5Mac should help until Apple releases another update. The first fix involves disabling Wi-Fi Calling from the iPhone’s Settings app. The other requires users to go to the Cellular Data Options menu in the Settings app and toggle the Enable LTE field from Voice & Data to Data Only.
Apple is yet to acknowledge the matter but given that iOS 12.1.3 is already in developer testing, it may not be long before the next update arrives to take care of this.
