If you are seeing the Cellular Update Failed message on your iPhone’s screen, you won’t be able to call anyone. In addition, you won’t be able to receive calls or use your device to browse the Internet.
More commonly the Cellular Update Fail message appears after the iOS 14 and iOS 15 updates, or as the result of hardware malfunction on some iPhone 7 models. Moreover, you will see a No Service message in the upper right corner of the screen instead of reception bars. As Apple will release iOS 16 this September, you may face the same problem after iOS 16 update.
There are a few things you can try that may make this problem go away, and in this article, we are going to take you through all solutions to this issue you have at your disposal.
The reasons you’re seeing the Cellular Update Failed message can be both software and hardware related. In most cases, the iOS update has failed to upgrade the cellular communication features which is the reason why you cannot make and receive calls or access cellular data. That is why checking if there is an available iOS update is the first thing you should do after you see this alert.
A system update may or may not resolve the Cellular Updated Failed problem, depending on what caused the issue in the first place. However, there a number of things you can try to restore your iPhone’s ability to make or receive calls. Let’s take a look at what you can do to make the Cellular Update Failed alert go away.
Besides the No Service message, your iPhone may also show the No SIM warning after displaying the Cellular Update Failed alert. That is why removing and reinserting a SIM card may fix the problem.
Simply switch off your iPhone and use the SIM card eject tool to remove the card from the device. Then switch the iPhone on, and return the SIM card tray to its slot. If everything went right the Cellular Update Failed message should disappear from the screen.
Activating the Airplane mode will disconnect the device from all cellular networks it may be connected to.
To put your device into the Airplane mode, you just have to open the Settings app and then tap on the Airplane Mode feature to enable it or disable it.
Although performing this action can fix minor cellular connectivity issues, you may not be able to fix the Cellular Update Failed issue by simply turning on and off the Airplane mode.
While still in the Settings app you can try enabling and disabling the cellular data. You can do this by tapping on the Cellular option and tapping on the Cellular Data feature to deactivate it and to switch it back on.
Although this is far from an ideal solution in some cases turning the WiFi Calling and Voice LTE options can help you fix the Cellular Update Failed problem. You can disable these two features while you are still in the Cellular menu of the Settings app.
Make sure that the switch next to the Wi-Fi Calling option is turned off, and tap on the Cellular Data Options submenu. Proceed to tap on the Enable LTE option and choose the Data Only feature in order to disable the Voice LTE.
Keep in mind that this method of fixing the Cellular Update Failed problem can limit the range of options your iPhone offers.
Outdated carrier settings can be the reason why you are seeing the Cellular Update Failed alert on your screen. To check if this is indeed the cause of the problem, you should head over to the General menu of the Settings app.
Enter the About menu, locate the Carrier feature, and tap on it. An update will start automatically within a few moments if it is available. Even though this is not a bulletproof method of solving the Cellular Update Failed problem, it may work if you haven’t updated carrier settings in a while.
