In this case, it’s likely just a random error which can be rectified by a simple reboot on your phone.

- Press the Power button for a few seconds.
- When the Power off menu option appears, tap OK to turn your phone completely off.
- After 30 seconds, press and hold down the Power key until the phone turns on.
Wait until the phone completely boots up then see if the error is gone. If it’s fixed then you’re good, otherwise you will need to try some other workarounds to fix the error.
Second solution: Remove and reinstall your SIM card.

- Turn your phone completely off.
- Insert the SIM ejector into the tiny hole on the SIM/SD card slot.
- Remove the SIM tray out from the slot.

This is likely the case if you happened to make some changes to your network settings that aren’t supposed to be altered.

Perhaps the new update automatically overrides your settings and thus resulting to this error. To rule this out from the possible causes, you can try performing a network settings reset. This will erase all your current network settings and restore the default values. That said, you will need to set up your Wi-Fi networks on your device when the network settings reset is finished.

Your phone automatically reboots when the reset is complete. Wait until it boots up completely then see if the error disappears. If not, then try updating your device software to the latest version available.
Fourth solution: Update software to the latest version available.

Updates not only bring in new features but likewise offer fix patches to address existing software issues on your device. Before you implement a new software update, don’t forget to back up all your critical data for safekeeping. Here’s what you should do then:
- Open the Settings app.
- Tap System update.
- Tap the option to Check for updates.
- Wait for your phone to check for updates. Make sure it’s connected to the Internet and sufficiently charged.
- If a new update is available, you will be prompted with an Install software message on your screen.
- When you’re all set to proceed, tap the option to Install now and then follow the onscreen instructions to implement the new software update on your device.
Reboot your phone to apply the new changes on the system. If that doesn’t work either, then you may have to perform system resets.
Fifth solution: Hard reset (factory data reset).
You may consider resorting to a master reset to wipe everything out from your phone’s internal storage including bugs and software glitches that might have prevented your device from recognizing the SIM card.
- Tap the Menu icon from the Home screen.
- Tap Settings.
