How To Fix Cellular Issue Detected
This popup error comes with two options: Settings and OK. The first one represents a shortcut for the Mobile Data settings while the second simply allows you to acknowledge the info.
If you tap Settings you get more info including:
“An update is required to use Mobile Data on this iPhone.”
1. Disable/Enable Cellular Data
The first thing that you should try is to disable Cellular Data and turn it back On. You can do this in Settings -> Cellular, or in the Control Center using the Cellular Data On/Off button.
Tip: You can also enable and disable Airplane Mode on iPhone to force the Cellular Data connection to restart!
2. Reboot iPhone
Next, a fresh start should flush minor glitches that could prevent iPhone to use cellular data.
Tip: Use the force restart trick. Click & release Volume Up, Volume Down and next press & hold Side Button until the screen goes black and an Apple logo is displayed.
3. Reinsert SIM
Another user informs that he managed to get rid of the Cellular Issue Detected popup by removing and reinserting SIM card.
Tip: Open the SIM tray with the dedicated SIM tray ejector tool, that should be found in the box that shipped together with your iPhone. You can also improvise one using a safety pin.
4. Carrier Settings Update
iOS 16 changes might require your carrier to update setting. You can check if and update is available from your carrier in: Settings -> General -> About
