How to fix Galaxy A80 “No SIM Card” error | SIM card not detected
Are you having a problem with your Galaxy A80 showing “No SIM Card” error? Well, this troubleshooting guide should help. Learn how to troubleshoot this problem by following our solutions below.
Galaxy A80 “No SIM Card” error fix #1: Reseat SIM card
If you have Galaxy A80 “No SIM Card” error, it’s possible that the SIM card may simply need to be reconnected to fix it. We’ve see this simple solution work on older Android devices before so it’s not a bad idea if you’ll try this on your new Galaxy A80. To remove the SIM:
- Turn off your Galaxy S10. This is important. Inserting a SIM while the device is on may result to corrupted data.
- With your phone’s screen facing you, remove the card tray. You can use the insertion/removal tool (or a paperclip) to unlock the tray by inserting it into the provided slot. This small hole should be visible on the top part of your device.
- Remove the SIM card from the tray. You can lift the card up from the bottom. To assist, use the opening on the opposite side of the tray to dislodge (using a fingernail or similar tool).
- Reinsert the card tray.
- Press in on the tray to lock it into place.
After removing the SIM card, wait for a few moments before inserting it back. Again, you want to make sure that the phone is off.
Galaxy A80 “No SIM Card” error fix #2: Perform soft reset
Sometimes, restarting the system can be a simple solution for fix bugs. If your Galaxy A80 “No SIM Card” error remains at this time, try to perform a soft reset. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your A80 using this method at least once a week to lessen the chances of bugs.
For some Galaxy A80, there may be a slightly different way to arrive at the same method. Here’s how:
- Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
- From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.
Galaxy A80 “No SIM Card” error fix #3: Get a new SIM card
In case there’s a problem with the SIM card itself, it’s also not a bad idea to replace it. Or, you can try to insert it into another compatible phone to see if its faulty or not. By compatible we mean a phone that works with your current network. If your SIM card is not detected by the second phone, it means that the card may be faulty. Try to wipe its gold contacts before inserting it. Sometimes, dust or dirt can block these metallic contacts and cause connection problems.
Galaxy A80 “No SIM Card” error fix #4: Clear cache partition
Android depends on a set of temporary files called system cache to load apps quickly. If this cache gets corrupted or outdated, a device may suddenly lag, freeze, or show signs of slow performance. At other times, uncommon glitches may occur as well as overall performance of the system may also be affected. To ensure that your A80 has good system cache, we suggest that you clear it once every few months. Here’s how to do it:
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe cache partition’.
- Press Power button to select.
- Press the Volume down key until ‘yes’ is highlighted and press the Power button.
- When the wipe cache partition is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
Galaxy A80 “No SIM Card” error fix #5: Reset network settings
Sometimes, network issues including No SIM Card error can be caused by incorrect network configuration. To check if that’s the case, try to reset the network settings of your device. Here’s how it’s done:
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap General Management > Reset > Reset network settings.
- Tap Reset settings.
- If you have set up a PIN, enter it.
- Tap Reset settings. Once complete a confirmation window will appear.
Galaxy A80 “No SIM Card” error fix #6: Check for bad app
A bad third party app can be another reason for an Android issue. If Galaxy A80 “No SIM Card” error started right after you installed a new app, try to delete that app and see if it helps. If you can’t remember anything or have no idea which app it might be, consider rebooting to safe mode. In this mode, all third party apps stop from running and only preinstalled ones will be allowed to load. So, if the problem is not present on Safe mode, you can assume a third party app must be causing it.
These are the steps to run your A80 to safe mode:
- Turn the device off.
- Press and hold the Power key past the model name screen.
- When “SAMSUNG” appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume down key when you see Safe Mode.
- Once on safe mode, try to charge the phone for at least 30 minutes and see what happens.
Safe Mode is not a solution by itself. It’s more of a tool to help you confirm if a bad app is causing a problem on an Android. So, if the phone detects your SIM card fine on safe mode only, you can assume that there’s an installed third party app causing it. If the error started after installing an app, make sure to delete the said app to fix it. If you can’t remember the app or if you have no idea what it might be, you can use elimination method to identify it. This is how it’s done:
- Boot to safe mode.
- Check for the problem.
- Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
- After you uninstall an app, restart the phone to normal mode and check for the problem.
- If your A80 is still problematic, repeat steps 1-4.
Galaxy A80 “No SIM Card” error fix #7: Factory reset
If nothing changed on safe mode and the problem remains at this point, you must consider wiping the phone with factory reset. Factory reset will return all software settings to their defaults. If the cause of the problem is software-related, factory reset might help. Learn how to factory reset below.

- Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
- Press and hold the Volume Up button and the Bixby button at the same time.
